Having a boat costs a lot of money, even when you are not using it, marina fees, etc. And once it is in the water most sailors never go very far from their “home marina” and sailing will be somewhat restricted. However, what if you could fold your trimaran and put it on a trailer, store it at your house, and go to a new sailing spot the next time?

Here are 6 of the best trailerable trimaran:

• The Dragonfly series
• Corsair Series
• Windrider 17

Choosing the best trailerable trimaran (a multi-hull with three “hulls”) will depend on crucial factors like speed, durability, design, and ease of transportation. This article is here to help you get started with your research and hopefully help you on the way towards your dream boat!

Cruising Trimarans That Can Be Transported

Cruising boats are made for multiday sailing either on the coast of your favorite sailing area or full-out blue-water ocean crossings. Extended living should be a priority in these designs.

1. The Dragonfly 25 and 28 (Dragon Fly Series)

Dragonfly is in the business of making the “best foldable trimarans on the planet” many would agree with this statement. Dragonfly is known for its commitment to easy trailering and ease of use, shown in designs for the Dragonfly 25 and Dragonfly 28.

The “Swing Wing” system on the linchpins is one of the key features of the dragonfly series. The system’s application makes it possible for the trimaran to narrow its beam as much as 50%.

Attesting to its Scandinavian manufacturing, most parts of the trimaran are made in-house. This guarantees quality and ensures that all used parts are above standard.

You don’t need to look further than the Dragonfly 25. Its centerboard slightly offset to port. Extra space is created in the main hull’s interior with a trunk buried under a settee. Performance-wise, the low drag and narrow hull shape allow the boat to reach blistering speeds.

Dragonfly 28 In Numbers

• Length: 8.75m
• Beam folded: 2.54m
• Max crew: 5-7 people
• Max Speed: 22+knots

Dragonfly 25 In Numbers

• Length: 7.65m
• Beam folded: 2.30m
• Max crew: 4-6 people
• Max Speed: 21+knots

2. Farrier F-22

New Zealand enters the trimaran manufacturing race with this premium sea goer. The vessel comes in two different versions: a performance variation with more horsepower and a full cabin cruising version. 

Compared to the dragon series the F-22 has the biggest allowance for space.

The F-22 is known for being one of the easiest trimarans to fold and load.

The sports version of the F-22 has some really good performance to offer. It has an aggressive spirit: you can mount a sail while leaving plenty of space for the boat’s fine entry and flared forward sections. The build quality is also topnotch—a lasting memorial to a principle that Ian Farrier always worked by: excellence.

Farrier F-22 In Numbers

• Length: 7.0m
• Beam folded: 2.5m
• Max crew: 3-5 people
• Max Speed: 20+knots

3. Corsair Series

This boat series has an exciting history. Farrier created it to promote his trailerable tri concept. However, the series is now independent with a top-class vehicle to its name.

The Corsair 760 is listed as providing some of the best performance and safety benefits to sailors.

Building off the spirit of excellence of the founder, the Corsair 760 has created a boat with comfort and racing potential. The boat can be tricky to handle at first, but it will be a breeze once you get the hang of it.

It is also worth noting that the corsair 37 is the largest trailerable trimaran on the market today.

Daysail Trimarans That Can Be Transported

Boats that are made for dayssailing are usually smaller, cheaper and more easily handled. They are perfect for those looking to enjoy a full day on the water in calm weather, but are usually less suitable for multiday events or rough sea sailing.

4. The Astus Models (20ft, 22.5ft, and 24ft)

If you’re looking for something small but still capable of doing day sailing, this 22.5-foot trimaran is for you. Built for speed and maneuverability, the Astus 22.5 has optional foils to optimize speed.

The modern design, coupled with the spacious interior, can fit up to four beds. Accordingly, this trimaran is suited for family outings. 

The Astus brand specializes in transportable trimarans, worth noting is that some models need a specific trailer whilst the smaller boats use a standard trailer.

5. Weta 14.5

The 2019 Weta trimaran is a 14.5-foot (4.4-meter) trimaran featuring a carbon frame, centerboard, rudder foil, and rudder shock. The hull is made from fiberglass and foam. The Weta is built for strength and speed based on these lightweight materials. 

The 2019 Weta trimaran is easy to sail and is worth considering whether you want to take a quiet sail, race with your friends, or take kids to a sailing lesson. It has a simple design and is easy to set up independently.

The small size makes it more suitable for daysailing in good weather rather than multiday cruising, although more experienced sailors will of course push the limits of this boat.

6. WindRider 17

The 17.4-foot (5.3-meter) WindRider 17 is one of the more versatile trimarans in the market. It packs high performance for a low cost. This trimaran has a light rotating mast to boost performance, and a full-battened mainsail optimizes visibility. 

This sailboat is made from rotomolded polyethylene, which is more durable than fiberglass and demands less maintenance.

The WindRider 17 has a comfortable interior and can fit six adults. This is an ideal choice for social sailing for a couple or a family and friends. It’s easy to ride, and a shallow draft allows easy maneuverability. 

What’s the Largest Trailerable Trimaran?

The largest trailerable trimaran is the Corsair 37 , this multihull is built for single-handed cruising while still maintaining the ability to comfortably seat 6 people.

The Corsair 37 provides comfort, speed, and safety. It also contains just enough space to accommodate amenities like a propane stove, a sink, and other equipment.

The vessel is designed to be a performance cruiser. It features an aluminum rotating wing mast, carbon fiber bowsprit, and premium deck hardware. The corsair can still cut through the water with ease despite its size, putting the wind in your sails.

What Is a Catamaran?

A catamaran is a boat with two hulls (a trimaran has three) connected by a bridge deck. Catamarans usually offer more space than both monohulls and trimarans of the same length. The catamaran is usually somewhat slower than a trimaran but faster than a monohull. They are usually made of fiberglass or carbon fiber.

Catamarans come in all shapes and sizes. You can find straightforward sailing catamarans, perfect for those who are only starting their sailing journey. Larger sailing catamarans have become extremely popular for long-distance sailing.

There are also power catamarans, they have huge diesel-powered engines (sometimes electric) and no sails. Also called “power cats”, these boats can reach 30+kts.

Can a Trimaran Be Trailerable?

As discussed above, some trimarans are possible to put on a trailer and move to another sailing area or to be stored at home. This is usually not possible with catamarans but is sometimes possible with the trimarans that are fitted with foldable amas (the two outer “floats” or “hulls”).

Some trimarans can be trailerable, this is mainly due to the ability to drastically decrease the vessels beam, sometimes as much as 50%. This allows the trailer plus trimaran to be below the legal requirements of the road.

Final Thoughts

It has proven difficult to beat the trimaran in terms of speed. Through the ages, this type of vessel has proven to be immensely enjoyable in all kinds of sailing activities. These can range from sea adventures to waterborne relaxation in your free time.

Trimarans come in various types, foldable, for cruising or racing, etc. However, there is a common factor: many of the small ones are trailerable. This makes them easier to move than most other types of boats.

Corsair Cruze 970

• By Tim Murphy; Photos By Billy Black
• Updated: August 7, 2014

Since 1985 the Corsair 31 has been a familiar trimaran on the racing and cruising scene. At yards in Australia and California, 303 of that model were built, with subtle design tweaks over the years. This year, the Corsair Cruze 970 replaces the 31 — and it’s all for the better.

Longer amas, as well as bows that are more plumb and hull forms with less rocker, add 20 percent more buoyancy to this boat, while retaining similar beam dimensions. The result is a more stable platform. The keel and rudder for the original 31 had been optimized for boat speeds between 3 and 10 knots. Incorporating the lessons from those 300 boats, today’s 970 features much thinner, higher-aspect-ratio foils that are optimized for speeds in the teens and higher. (A note to those who haven’t sailed Corsairs before: Those boat speeds are real. Try it!)

Living spaces, both inside and out, are improved in the 970. Boat of the Year judge Mark Schrader was a dealer for Corsair years ago and raced the boats many miles. “They’ve added two very comfortable park benches in the cockpit,” he said of the 970. On the 31, he said, “there wasn’t really any place for more than four people to sit, stand or do anything without hugging each other.” The 31 was offered with either an aft cabin or an aft cockpit arrangement; the 970 deftly manages to make space for both, while also adding headroom in the cabin. Using careful building techniques, including vacuum bagging, Corsair has added more furniture in the cabin yet kept the weight the same.

As with other Corsairs, the amas of the 970 can be folded inboard for trailering. The well-refined mechanisms for doing so are the same as in the previous versions.

We sailed the 970 in light air. With the screacher up in 8 to 10 knots of breeze, we posted 6.6 knots just above 60 degrees apparent, then cracked off and made 7.6 knots. Steve Marsh, a Florida-based Corsair dealer, said you can sail 15 degrees closer to the wind with the blade jib. Propulsion on the boat we sailed is a Yamaha 9.9-horsepower outboard on the transom, with a steering arm affixed to the 970’s tiller and remote engine controls in the cockpit. The 970 offers no inboard option.

Several years ago Australia-based Seawind Yachts purchased the Corsair brand. These days both lines are built at a single factory in Vietnam. The construction quality is quite good — better than the California-built 31s, observed Schrader. The company offers a five-year warranty on the structure, as well as manufacturers’ warranties on installed hardware.

Schrader summed up the pleasures of this boat: “You can park it on the beach. You can run around on the trampolines. You can get into a foot and a half of water. It’s your platform to go park in some little lagoon somewhere.”

And yet, all that idyllic parking doesn’t account for even half the fun. Because in getting there, you’ll learn what boat speeds of 20-plus knots feel like.

The new Corsair is a fast cruising platform, light and bright belowdecks, but with a bit less elbow room than you'd find on a 36-foot monohull, and pricy. For many, these are worthy trade-offs.

Twenty years ago, when Corsair Marine first entered the U.S. market with the F-27 trimaran (which PS reviewed in September, 1990), “family” multihulls were not generally thought to have stellar sailing characteristics. They were difficult to tack. They did not sail well to weather. They required large parking places. In ensuing years, Corsair’s 24- to 31-footers have helped change the perception in the marketplace. These boats are fast, sail well, and are easily trailerable since they fold to 8′ 6″. The major shortcoming has been accommodations that are one cut above camping. The introduction of the Corsair 36 has allowed the company to step into the real world of “cruising comfort.”

Company History Corsair Marine was founded in 1983 by John Walton (of the Wal-Mart family), who envisioned production of a fast, easily trailerable trimaran. A compromise would be accommodations limited by the narrow beam of the main hull.

Walton convinced Ian Farrier, a talented multihull designer, to abandon a thriving practice in Australia, move to California, and execute his vision.

In a morning-long session with PS, Farrier, who sees the world only through multihull lenses, elaborated on the many reasons he considers multis preferable to monohulls, not the least of which is that, “Corsair boats are unsinkable. They have watertight compartments, so even if they pitchpole the crew can crawl inside a capsized hull and have air to breathe and protection from the elements. In a monohull, the crew will most likely be adrift in a liferaft.”

Walton and co-owner Paul Koch, also an Aussie, succeeded, despite the complicated, people-intensive construction process necessary to produce foldable boats capable of withstanding loads endured at sea and on the highway. A by-product was pricing that ratcheted the boat to the very high end of the market when measured on a cost-per-foot basis.

Prior to introduction of the Corsair 36 in February, 2003, the company’s line included the 24-, 27-, and 31-foot models. Boats were built primarily in Chula Vista, California, though the first six F-31s, introduced in 1992, were built at Tillotson-Pearson (TPI) in Rhode Island.

In 1994, Koch purchased Walton’s share and consolidated all of the manufacturing operations at the California plant, where boats are now built.

In its first two decades, Corsair has produced 1,260 boats; annual production is typically 72-75 boats, Koch says.

The 36-footer has been well-received; seven have been ordered since its introduction.

Design Though Ian Farrier is credited with the design of the first three models, and influenced the 36-footer, his affiliation with Corsair ended in the mid-’90s. Paul Koch says that a team of in-house engineers and outside consultants are responsible for the design of the 36.

All of the boat’s design elements— hull, deck, and sailplan—bear a strong resemblance to its predecessors, but the extra LOA allows more graceful lines. Her long, low profile is accented by a downward-sloping cabintop and long, narrow, dark windows. Viewed from the bow, the hull presents a fine entry. The amas also have a fine entry, and near-flat sheerline offset by very round shapes and downward curving bottoms.

However, the new model adds enough load-carrying capability to provide creature comforts suitable for extended cruising. She’s only 900 pounds heavier than the F-31, and performs as well under sail.

All of the Corsair boats, when folded, have the appearance of a giant Daddy Longlegs. The 36-footer also features a tilt-up rudder and shallow draft that allows her to anchor in less than two feet of water, or sail onto a beach. In tight quarters, she can be folded when at anchor.

With a folded beam of 9′ 10″ she’s wider than other models, so owners may be required to secure wide-load permits in some states. To assist owners in avoiding the expense of acquiring a trailer ($7,638), and, perhaps, more powerful tow vehicle, the company has organized fleets of truckers that transport the boats for $1.50 mile, including the cost of a driver.

After the introduction of hull #1 (the boat we tested), input from dealers and consumers at two boat shows brought about a few design modifications and refinements.

Deck and Rig Layout The organization of spaces and layout of gear on the C-36 is almost a carbon copy of its predecessors.

The cockpit is as big as those on monohulls of about the same LOA—wide enough to seat a crew of 4-6 comfortably, and narrow enough to allow a shorthanded crew to work large headsails. The regular cockpit seats are well-proportioned, and there’s additional seating set into both sides of the stern pulpit. These mesh-bottomed seats are good places to be while underway, since they’re elevated, clear of the action, and softer to sit on than fiberglass.

The cockpit is enclosed by a pulpit, and the path forward is atop the cabin or on the trampolines, so a certain amount of agility is required to move forward when necessary. Because of the narrowness of the main hull, shrouds are located on the amas, not close at hand, and the deck is devoid of handrails and lifelines. The trampolines fitted between the hull and amas provide a sturdy, though bouncy, platform.

Corsair outfits boats with high-quality hardware. On the 36, all of the deck gear, including winches, is supplied by Harken or Spinlock.

In its standard configuration she is fitted with Harken B40 self-tailing winches on the cabin top, two Harken B42.2 winches in the cockpit, and two Harken B32.2 self-tailing halyard winches on the mast. Working halyards at the mast instead of leading them aft to the cockpit makes sense, according to multihull sailors, because multihulls sail flatter, and a walk to the mast and back doesn’t present as much of a challenge as it does on a heeling monohull. It also reduces cockpit clutter and friction.

The mainsheet is located at the end of the boom and led to a Harken traveler track that spans the stern, an arrangement that produces excellent sail shape, allows the helmsman to trim the sail, and also reduces the amount of clutter in the cockpit. The system is fitted with a Harken Big Boat Series double-block and tackle led to cockpit winches.

To maximize performance off the breeze, a spinnaker control kit ($3,720) adds two winches in the cockpit, carbon fiber bowsprit , and sheets, blocks, control lines, and cleats necessary to complete the installation.

Corsair is constructing aluminum masts at its factory from extrusions produced by Sparcraft. Our test boat was equipped with a double-spreader rig with swept spreaders and stainless steel wire rigging. At the time of our test, Koch was considering replacing the double spreaders with singles, because, “the second set was redundant.” He has since made that change.

The standard rig is a 3/4 fractional. With the addition of spinnaker gear and bowsprit, a second stay is attached to the mast approximately one foot higher and terminated near the end of the sprit.

The rotating mast is deck-stepped on a ball atop a Delrin bearing that allows it to rotate 45 degrees. Its movement is controlled by a block and tackle arrangement and stainless steel ring on the aft side of the mast. The result is a significantly more aerodynamic presentation of the mainsail to the breeze, which translates to acceleration and speed when sailing to weather or on a reach.

Two steps on the stern provide access for swimmers. Since the rudder is transom-hung, an outboard is located off-center in a hull recess.

Belowdecks When Corsair stretched the F-27 to 31′, owners were rewarded with living spaces large enough to be marginally comfortable on an extended trip. With more stretching, the C-36 still doesn’t have as spacious a main cabin as a 36-foot monohull because of her narrow beam—but she closes the gap significantly.

The accommodations are an excellent example of what can be accomplished using fiberglass and other weight-saving materials, since virtually all of her components are exposed. In fact, there’s so much exposed white in the fiberglass and headliner that only the red cushions and cabin sole provide some relief from the brightness. In addition to concealing wiring, the headliner also acts as a sound deadener. It’s stuck to the overhead with hook-and-loop fasteners. We were concerned about sagging, but found it difficult to remove. If the glue behind the hook-and-loop tapes fails eventually, it will be easy enough to replace.

The area is well lit by two ports on each side of the cabin, and light entering from the companionway. Our test boat had hatches only over the head and the forward berth. In subsequent boats Koch has added a third in the main cabin.

Given more volume below, designers were able to increase standing headroom to 6′ 6″. The saloon measures nearly 6′ from companionway to the head on the port side. A proper C-shaped, elevated dining area, also to port, converts to a 6-foot berth, tapering in width from 41″ to 30″. The galley is to starboard, aft of a second settee that can double as a berth for a small person, and the V- berth.

Stowage space in the boat is at a premium. Although the amas have large storage areas for light gear, accessing those spaces can be a pain, as is true on all cruising trimarans.

The dining table is constructed of fiberglass, but finished to give the appearance of a shiny wood grain. Similarly, the vinyl sole looks like teak, but is a lightweight composite that comes with a 10-year guarantee. Since the boat has no nav station, the dining table is a likely candidate. Odds are, the VHF radio will be mounted on the companionway bulkhead, and instruments on the companionway hatch, close at hand to a navigator working below.

The galley on our test boat was equipped with an optional stainless steel, two-burner propane stove, and double stainless steel sink. A clever arrangement is a recessed faucet that pops up when needed. All are mounted in a fiberglass cabinet with a tiny storage area below. An insulated ice box is standard; refrigeration and pressure hot and cold water are available as options.

The head is a low-maintenance, smoothly finished fiberglass pan measuring approximately 40″ x 35″, consisting of a molded vanity/sink combination with a medicine cabinet outboard, toilet, and handheld shower. It will prove functional, utilitarian, and just large enough for average-sized adults. It will not be confused with the space on a typical 36-foot cruising monohull. The head shares space with a fiberglass shell housing the daggerboard. The shell is so well finished and fitted in as to be nearly invisible. (The daggerboard is constructed of balsa encapsulated in fiberglass.)

The V-berth offers accommodations for two in an enclosed area that has a hatch overhead and Halogen lights and ports on each side. The berth measures 6′ 4″ long on the centerline. It’s 5′ wide at the head, and fitted with 4″ thick cushions. The hull liner is a combination of fabric and shiny fiberglass. Storage and a holding tank are under the berth.

A second berth with a queen-sized mattress is located below the cockpit sole. It’s accessed via two hatches aft of the cockpit, in what would be called the lazarette area, or by removing companionway steps. Two ports provide ventilation at anchor. This is the most spacious sleeping area, and will be fun for kids to climb in and out of (especially since it also hosts the transparent escape hatch). However, the mattress will be ruined quickly if people climb down there with dirty or wet deck shoes, and the space will be noisy if used while underway.

A large storage area under the steps provides a bed for an optional diesel engine. In our view, the 20-hp outboard and a solar panel or two will be the better choice. Don’t overburden a butterfly.

Construction The high cost of Corsair’s boats is attributed to several factors, not the least of which are tooling costs associated with a boat that has more than 30 different moldings, including 10 in the deck and hull, and 11 in the areas belowdecks, as well as two amas, four akas (crossbeams), and all the precision-engineered parts that allow the whole thing to be folded up.

In addition, the company uses high-tech raw materials, including vinylester resins, carbon fiber, double-bias fabrics with Kevlar, and a vacuum-bagging and curing process that relies on precise blends of fiberglass, resin, and catalysts.

Since light weight and high performance are closely related, Koch says hull #1 was built to within 200 pounds of her design weight. Subsequent boats have been further reduced by 100 pounds, mostly by eliminating a set of spreaders and their related parts.

The lamination schedule consists of a layer of NPG gelcoat, a skin layer impregnated with vinylester resin to prevent blistering, and multiple layers of uni- and bi-directional fiberglass. Kevlar is laid in high-stress areas on the bottom, daggerboard trunk, and at bulkheads.

Akas are constructed of layers of fiberglass, carbon fiber, and foam, which increases stiffness. Additional strength and buoyancy in the amas is afforded by watertight bulkheads.

Performance PS editors have sailed most of the Corsair boats over the years, often in racing conditions, and can attest to their speed under sail and their strong construction. This time, we wanted to see if the company could add creature comforts without compromising performance.

Koch’s hopes were for a 15-knot cruiser. “I was surprised,” he told us, “when she sailed at 20 knots during early testing of a prototype in Australia.”

Aside from the long waterline and low wetted surface of the main hull, and the light overall weight of the boat, the biggest contributor to performance is the rotating mast, which supports a square-topped, full-battened mainsail with oversized roach. The advantage of the rotating mast is that it presents a clean, aerodynamic shape to the wind, as opposed to the slab of aluminum of a fixed spar. As we learned during our day-long test sail, trimming the main involves driver and trimmer coordinating their point of sail and mast position. In heavier air, “de- rotating” the mast brings it closer to the apparent wind, flattening the mainsail, and spilling wind to prevent heeling.

We sailed on Biscayne Bay in winds that built from 5 to 15 knots. We had a crew of six—one crewmember stretched out on the V- berth, another snoozing on the trampoline, and four of us trimming sails.

Several manufacturers were testing their new products to see how they performed, using a two-year-old Corsair F-31 as the rabbit. Koch’s goal was to compare the performance of the old and new boats.

From a mechanical standpoint, the boat is easily managed from the cockpit, except that the main is hoisted at the mast. The genoa is on a furler, and main and jib sheets are close at hand.

With Steve Marsh of the Finish Line, a dealer in Stuart, at the helm, we sailed close-hauled in 8-12 knots of wind with boatspeed consistently registering 8-10 knots. She sailed higher and tacked faster than other boats in the fleet, and as quickly as the F-31. She seems to pivot on her daggerboard, and tacked through 95-100°.

When the wind angle moved deeper than 35°, we hoisted a “screacher,” essentially a high-clewed, 180% drifter, and speed increased to 12-15 knots. She heeled 5-10°, carving through a modest chop on the surface. Performance in these conditions was as good or better than the F-31.

The sheeting angle of the headsail is adjusted via a canvas strap attached to the hull beams. It allows the clew position to be moved in and out, much like a barberhauler.

As the wind backed, we punched through small swells by elevating the height of the screacher tack, easing the tack line from the cockpit.

A big difference between monohulls and multihulls is that when a puff hits, most monohulls will use up some of that force by heeling to it, while a good multihull will stay firmly on its feet and use the force for acceleration. The C-36 does this admirably.

Steering through a jibe with a screacher on the sprit-equipped boat is challenging, since the screacher moves between forestay and furler. Once the boat is headed dead downwind and the boom centered, the jibe is completed by quickly turning to weather to fill the sail while the crew tensions the new sheet and the mainsail is eased.

The boat moved easily through the harbor at 5-7 knots with the quiet 20-hp. four-stroke outboard.

Price The current base price for the Corsair 36 is $199,000, including the 20-hp. motor, FOB Chula Vista. In reality, a well-equipped boat will cost closer to $215,000-$225,000, including sails and trailer ($7,638) but without race gear or spinnaker. Options include the propane stove with hot water system, ($875); pressure water ($2,275); Standard Eclipse VHF radio and antenna ($645); spinnaker control kit ($3,720), and screacher controls ($1,969), which require the spinnaker controls.

Conclusion When we first examined Corsair boats years ago, it was with a skeptical eye. While sailing characteristics weren’t questioned, folding tris are complex. We worried about the lightweight construction methods and durability; the toughness of the ama-aka combination; viability as a trailerable vessel, and high price.

Time has alleviated most of those concerns, even the ones about cost, because, in this case, you’re paying for things that work.

The C-36 is certainly fast. Not many boats this size, even other multihulls, will cruise easily at 12-15 knots. She’s also versatile. Her shallow draft offers opportunites to picnic on the beach, or anchor close to shore, away from the mooring field, and yet her foldability means that she can hover in crowded areas when necessary. And she can be towed down the highway for cruising or racing far afield.

Corsair says the boats can be rigged, unloaded, and ready to sail in an hour. Based on real-life observations, we think the time will vary with the size and physical prowess of the crew.

Cockpit seating is large enough to seat six comfortably underway or at the dock. Down below, it’s bright and clean-looking, but creature comforts don’t compare in size or appointments to a middle-of-the-road 36′ monohull equipped with nav station, wine rack, and entertainment center—if that’s your bag. On this boat, the entertainment is found underway.

The high initial cost for trailerable folding trimarans tends to produce sticker shock, since a similar-sized monohull can be purchased for 25% less. On the upside, well-maintained, newer used tris are selling for 75-85% of their original price.

This new boat will appeal to sailors who prefer sleekness and speed to “cushiness,” which is not the same as “comfort.” Aboard boats, comfort is linked to function, and by that definition she’s comfortable enough.

Early warning early warning radar "Voronezh"

Video: Early warning early warning radar "Voronezh"

2024 Author : Matthew Elmers | [email protected] . Last modified: 2023-12-16 21:49

Voronezh stations are designed to detect and track ballistic and cruise missiles and other aerodynamic objects.

On the Internet and in print, you can find the wrong name for these stations - over-the-horizon or over-the-horizon radar.

Since December 1 of last year, they have become part of the Russian Aerospace Defense Forces.

The main feature of the Voronezh radar station is its high factory readiness.

The first to develop and put into operation a meter-range radar station "Voronezh-M". The next development was the Voronezh-DM radar. The third radar data model is Voronezh-VP.

The first steps towards the creation of radar stations with VZG were taken in 1986 during the creation of the radar station DO "Selenga".

VZG provides installation period for these radar stations no more than 18-24 months.

The stations consist of 23 units of sets of equipment.

Voronezh uses hardware and design solutions that allow assembling a system from a set of ready-made factory assemblies with characteristics that meet the operational and tactical requirements of the installation site. All issues of energy resource management are solved programmatically and technologically. Built-in control and high-tech control system reduce maintenance costs.

Service personnel are accommodated in standardized containers that have a system for ensuring temperature characteristics.

The designers have worked out the range of cabinets - "Voronezh" has 12 types of cabinets, of which the cabinets with transmitting and receiving equipment and the AFD control system are serial. There are 22 non-serial cabinets on the radar station of the Voronezh subsidiary, they were placed in 3 containers, in which the equipment for monitoring temperature characteristics is also installed.

Receiving and transmitting equipment in the "Voronezh" radar station is located in the large antenna complexes of the VZG. They are ready for transport and assembly units.

The installation of these complexes takes place on fast assembly support structures. This leads to the rapid construction of an active antenna pattern. This block-complex assembly reduces losses in the transmission and reception paths, reduces the temperature and, in general, gives a high indicator of the efficiency of the antenna device. In addition, this layout allows for upgrades. Emitters are located at the end of each container.

The radar antenna DO SPRN "Voronezh" uses a method of creating subarrays for reception, which reduces the amount of equipment used without lowering the characteristics of the antenna pattern. The method is implemented on the mutual overlap of sublattices and the use of special amplitude distributions in them.

The stages of the transistor design of the transmitting amplifiers in the AFD interact in a "hot collector" manner. This allows the transmitting equipment to be cooled with "outboard" air coming through the ventilation equipment, which is part of the technical equipment. This "live" ventilation made it possible to abandon the overall thermal stabilization and cooling systems.

The hot air cooling circuit is distributed to all antenna boxes using an integrated air duct system.

The temperature indicators on the end switches of the air ducts of the installed modules are on average no more than 45 degrees. At low temperatures, in winter, the circuit is closed, and warm air is used to heat the antenna boxes. Warm air in the circuit is diluted with cold outside air to maintain a certain temperature.

The equipment of the receiving channels has not only digitization of signals, but also built-in processors for initial digital processing and verification control of the receiving paths. This approach saves computing facilities "Voronezh" and channels for transmitting information, and reduces the loss of processed signals, using digital methods to stabilize the non-identity of the used phased array channels.

Digital signal processing occurs at the carrier output frequency with the following allocation of quadrature elements, which made it possible to qualitatively reduce the loss of processed information.

Computing equipment used for primary and secondary processing is made on a "server" computer with an open architecture of information processing in real time. The computer is unified for all types of promising topics. It has two types of processor cells and 2 buses: the VME bus and the user bus. Constructive computer box - "Euromechanics". The performance of the solution is up to one hundred billion operations per second. The computer has unlimited possibilities for upgrading and expanding. The occupied area is half of a standard cabinet for Voronezh equipment. Consumes 1.5 kW / h. Service is not provided. Guaranteed operating time 80 thousand hours.

Functional and technical control is performed as peripheral coprocessors, which are built into technical equipment, combined with a central coprocessor by a high-speed interface. This made it possible to reduce the volumetric dimensions of the equipment, increase the reliability of the information flow and functional control.

The Voronezh radar station uses programmed regulation of the potential in the sector of responsibility for range, angles and time, the mode of saving consumed resources.

Software adjustment with these modes makes it possible to quickly change the power consumption of the radar station in normal, combat and readiness for combat use modes, to equalize the energy consumption in the working sector of the radar station.

During the installation of the head radar of the DO SPRN "Voronezh-DM" near the city of Armavir, for its power supply, a power line with a total length of more than eight kilometers was extended, communications and roads were built.

At the installation site of the radar, a checkpoint was set up, a BVM, facilities for water intake, an electrical substation, a fire station, and an underground shelter were installed. The premises have been modernly decorated. For the personnel of the radar, they created quite comfortable conditions for living and performing combat missions. For recreation and physical training, there is a training tower, a volleyball court and a hundred-meter course for training fire station personnel. The entire area is lit and fenced around the perimeter. Seedlings of trees and shrubs have been planted.

Since the start of construction, mid-2006, a set of works has been carried out on 58 units of construction projects. Completion of construction - 2009. Contractor - USS No. 7 Spetsstroy RF.

The main characteristics of the radar "Voronezh":

- consumption power: "DM" - 0.7 MW, "VP" - up to 10 MW;

- detection range: "DM" 2500-6000 kilometers, "VP" - 6 thousand kilometers;

- target development: "DM" up to 500 units.

Voronezh series modifications:

- The Voronezh-M early warning radar was built in 2006, designation 77Ya6. It is a low-potential VHF station;

- The Voronezh-DM early warning radar was built in 2011, designation 77Ya6-DM. It is a mid-potential station of the decimeter range;

- The Voronezh-VP early warning radar is planned to be completed in 2012, designation 77Ya6-VP. It is a high-potential broadband station of possibly millimeter-wave range.

Economic indicators of station construction:

- Armavir Voronezh-DM - 2.85 billion rubles;

- Pioneer Voronezh-DM - 4.4 billion rubles;

Location of stations "Voronezh":

- "Voronezh-M" is located in the Leningrad region, since 2009 has been on alert, provides control of the territory from Svalbard to Morocco;

Russian military carrying out necessary “combat measures” in southern city of Voronezh, governor says

From CNN's Uliana Pavlova

Russian military are carrying out the necessary “combat measures” in the southern Russia city of Voronezh, the region's governor said.

Alexander Gusev posted a brief update on his Telegram channel, as geolocated videos emerge showing Wagner fighters and vehicles on the move along the M-4 highway that leads to the city of Voronezh from southern Russia.

“As part of the counter-terrorist operation on the territory of the Voronezh region, the armed forces of the Russian Federation are carrying out the necessary operational and combat measures. I will keep you updated as the situation develops,” Gusev said.

Chechen leader Kadyrov condemns "treacherous march" of Prigozhin, urges support for Putin

From CNN's Tim Lister and Anna Chernova

Chechen leader Ramzan Kadyrov has condemned the actions of Wagner chief Yevgeny Prigozhin and pledged his support to the Kremlin.

Addressing Wagner fighters, Kadyrov said: “Whatever goals you are given, no matter what promises you are told -- the security of the state and the cohesion of Russian society at such a moment is above all else! See how our enemies in the West are taking advantage of this situation….These are the expected consequences of Prigozhin's treacherous march.” 

He also spoke of a “vile betrayal” by Prigozhin. 

In a long statement on Telegram, Kadyrov said: “I have repeatedly warned that war is not the time to voice personal grievances and resolve disputes in our rear. The rear must always be calm and reliable. Imagine how the guys in the trenches feel now, in the face of which there is an enemy, and behind their backs a treacherous adventure. We are talking about stability, about the cohesion of the state, about the security of citizens.”

Kadyrov continued: “We have a Supreme Commander-in-Chief, elected by the people, who knows the whole situation to the smallest detail better than any strategist.”

Referring to President Putin ’s address to the nation Saturday, he said: “Vladimir Vladimirovich quite rightly noted in his address to the nation -- this is a military rebellion! There is no excuse for such actions! I fully support every word of Vladimir Vladimirovich Putin!

“What is happening is not an ultimatum to the Ministry of Defense. This is a challenge to the state, and against this challenge it is necessary to rally around the national leader: the military, security forces, governors, and the civilian population.”

Kadyrov’s statement ends: “The rebellion must be crushed, and if this requires harsh measures, then we are ready!”

Some context: Wagner chief Yevgeny Prigozhin claimed Saturday to have seized control of key military facilities in Rostov and Voronezh, pledging to move on to Moscow if Russia's Defense Minister Sergei Shoigu and top general Valery Gerasimov, did not meet with him.

Earlier, the official Russian news agency TASS reported that traffic had been blocked on the M-4 highway past Rostov-on-Don towards Aksay.

“All cars moving from Rostov-on-Don towards Aksay are being redirected back in the city, and police checkpoints have been reinforced,” TASS reported.

Russian Foreign Ministry urges unity around Putin to prevent "civil strife"

From CNN's Anna Chernova

The Russian Foreign Ministry has issued a call for unity in Russia in order to prevent the potential threat of “civil strife.”

“We have one commander in chief [Vladimir Putin]. Not two, not three. One. And he urged everyone to unite,” spokeswoman Maria Zakharova said in a Telegram post, echoing sentiments expressed by other government officials.

“The enemy is just waiting for our civil strife,” she added.

Zakharova urged the men of Russia to unite despite their differing views. “Behind you are children, women, your parents! Behind you is the country. Behind you is everything that you defend with weapons in your hands. Behind you are the graves of those who did not spare themselves. You are future generations. Hold on and don't give in."

Zakharova concluded her message by urging Russians to stand strong.

“Today we are all being tempted, our strength tested. Don't give in! Together with the President! May God keep us!” she added.

Her words of defiance come as Wagner chief Yevgeny Prigozhin claimed Saturday to have seized control of key military facilities in Rostov and Voronezh, pledging to move on to Moscow if Russia's Defense Minister Sergei Shoigu and top general Valery Gerasimov did not meet with him.

Voronezh governor disputes rumors about military equipment moving through the region

From CNN’s Uliana Pavlova and Anna Chernova

Rumors of military equipment moving through Russia's southern city Voronezh amid reports of Wagner fighters also traveling in the region, have been disputed by its governor Alexander Gusev.

“A lot of unreliable information is now being published on social networks about the alleged movement of columns of military equipment through the territory of the Voronezh region,” Gusev said in a statement Saturday.

“The legislation of the Russian Federation provides for liability for the dissemination of such messages,” he added, asking people to only follow information from official sources.

"I also ask the media to take a responsible approach to posting information,” Gusev said.

The Russian news agency RIA Novosti quoted its correspondent in Voronezh as saying that “access to the buildings of the FSB and the Ministry of Internal Affairs in Voronezh is blocked, the police are on duty.”

Major Russian highway disrupted amid reports of Wagner presence

From CNN's Tim Lister

Motorists on a major highway in southern Russia have been advised to avoid the route, amid reports that convoys of Wagner fighters are using it.

The warning was posted on Telegram by the company Avtodor, which operates Russian highways.

“Drivers, Attention. Please choose routes around the M-4,” the message read.

The M-4 runs north from Rostov to Voronezh and onto Moscow.

Wagner chief Yevgeny Prigozhin claimed Saturday to have seized control of key military facilities in Rostov and Voronezh, pledging to move on to Moscow if Russia's Defense Minister Sergei Shoigu and top general Valery Gerasimov, did not meet with him.

European leaders and NATO monitor situation in Russia

From CNN's Joseph Ataman, Sharon Braithwaite, Antonia Mortensen and Uliana Pavlova

NATO is "monitoring the situation" in Russia, a spokesperson told CNN Saturday, which the European Union has also said it is "carefully" doing.

"We are following the situation carefully and are in permanent contact with our Ambassador in Moscow and continuing our internal consultations with our Member States," EU spokesperson for Foreign Affairs and Security Policy Nabila Massrali told CNN.

"What we are witnessing is an internal Russian issue," Massrali added.

Other European leaders have also commented that they are monitoring the events.

French President Emmanuel Macron is following Russia "closely," the Elysee Palace said Saturday.

“The President is monitoring the situation closely. We remain focused on supporting Ukraine," the Elysee said.

Estonia's Prime Minister Kaja Kallas tweeted that they were also following developments and trading information with allies.

"Border security has been strengthened. I also urge our people not to travel to any part of Russia," she said after assuring they do not face any direct threat.

Similarly, Poland's President Andrzej Duda said they were watching the situation on an "ongoing basis."

"Due to the situation in Russia, we held consultations this morning with the Prime Minister and the Ministry of National Defense, as well as with the Allies. The course of events beyond our eastern border is monitored on an ongoing basis," Duda tweeted Saturday.

Meanwhile, Belarus President Alexander Lukashenko and Russian President Vladimir Putin spoke by phone Saturday morning, Belarusian official news agency reported.

"The Russian president informed his counterpart about the situation in the country,” BELTA said.

Belarus, which shares borders with both Russia and Ukraine, was a key ally to Putin when the war started February last year.

Anti-terrorist regime introduced in Moscow and Voronezh regions

The Russian National Anti-Terrorism Committee announced the introduction of a counter-terrorist operation regime in Moscow, the Moscow region and Voronezh region.

"In order to prevent possible terrorist acts on the territory of the city of Moscow, the Moscow and Voronezh regions, a counter-terrorist operation regime has been introduced," the statement said. 

According to Russian state media, this is the first time that the counter-terrorist regime has been announced in these regions. 

The measures were announced as the head of the Wagner private military group, Yevgeny Prigozhin, was accused of mounting an armed revolt against the Russian state. 

The counter-terrorist regime includes, but is not limited to:

• document checks
• strengthened protection of public order
• monitoring telephone conversations
• restricting communications
• restricting the movement of vehicles and pedestrians on the streets.

Key lines from Putin's address

Russian President Vladimir Putin warned that those on the “path of treason” or armed rebellion will be “punished” after the head of the Wagner paramilitary group said his troops had taken control of military facilities in two Russian cities, plunging the country into crisis.

Here are some of the key lines from Putin's address:

• Putin vowed a harsh response and punishment of those involved in armed rebellion. "Any actions that fracture our unity" are "a stab in the back of our country and our people,” he said.
• Putin said the armed forces "have been given the necessary orders" and "decisive action will also be taken to stabilize the situation in Rostov." 
• He said, "additional anti terrorism, security measures have been imposed in Moscow, Moscow region and a number of other regions."
• Putin appealed to Wagner forces "pushed into the provocation of a military rebellion," saying at this time, "we require unity, consolidation, and responsibility."
• Putin described events in Rostov as an insurrection. He said the situation in Rostov "remains difficult during the armed uprising" and "the work of civil and military administration is basically blocked."
• Putin said the country had been "betrayed by those who are trying to organize a mutiny, pushing the country toward anarchy and fratricide." He said "excessive ambition and vested interests have led to treason."
• Putin said it was a "blow to Russia," adding, "Internal turmoil is a mortal threat to our statehood, to us as a nation."

Putin says Wagner's "betrayal" is a "stab in the back of our country and our people"

From CNN's Josh Pennington 

Russian President Vladimir Putin said Wagner's "betrayal" and "any actions that fracture our unity," are "a stab in the back of our country and our people."

"What we are facing is precisely betrayal. Excessive ambition and vested interests have led to treason. Betrayal of one's country, one's people, and the cause for which the soldiers and commanders of the Wagner group had fought and died, side by side with our other units," Putin said. 

Putin called Wagner actions "internal treachery," saying that "all kinds of political adventurers and foreign forces, who divided the country and tore it apart, profited from their own interests. We will not let this happen again. We will protect both our people and our statehood from any threats, including internal treachery."
