Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The WETA 4.4 is now manufactured by Xstreme Sailing Products of Indonesia. Retractable beam: 5.58’. Sail area – gennaker 8.0 m2/86.1 sq.ft.

Compact Weta Trimaran Screeches Past the Big Boys on Biscayne Bay

Mini-multihull with aerospace-like attention to detail fills niche of high-performance day sailor.

The new Weta trimaran is designed in New Zealand, built in China, and imported into the U.S. by Nor Banks Sailing of Duck, N.C.

Photo by Billy Black

When it comes to the pure love of sailing, its hard to beat a small, light efficient boat whose sole mission is to harness the wind rather than provide a home afloat. And now that Hobie and others are moving toward heavy, flexible, roto-molded plastic, and lower performance “beach boats,” its no surprise that a new mini-multihull has come along to fill the niche.

During the few days immediately following the Miami Boat Show in February, Biscayne Bay, Fla., becomes a multihull playground where shallow-draft cats and tris strut their stuff. In a David-and-Goliath replay, the 14-foot-6-inch long Weta trimaran streaked like an agile mouse amidst a herd of elephants. The big cruising cats certainly offer sumptuous accommodations, but they lumbered in the fickle 10- to 12-knot breeze that touched down and lifted off the bays green water. At the same time, the Weta 4.4 scooted off on double-digit reaches, accelerating with each puff, and ghosted through the lulls. If enjoying an active sailing experience on Miamis aquatic frontyard was the plan of the day, the Weta won hands-down.

Conceived in New Zealand by father-and-son team Roger and Chris Kitchen, and designed with collaborative help from a handful of experienced sailors, this elegantly simple and finely built boat is a glowing example of mission accomplished. The company principals, an ex-mathematics teacher and his highly skilled Laser-racing son, bridged both a generation and engineering gap, and came up with the performance boat both had envisioned. The big challenge, however, was in creating a cost-effective boat with the strength-to-weight ratio needed for performance sailing. And a good part of the Wetas challenge was to mate an efficient design concept with the careful use of high-tech and mainstream materials along with exacting composite boatbuilding techniques.

Construction

A carbon-fiber and E-glass tubular framework connects the outer amas to the hull and successfully spreads rig and hull loads. The mast and sprit are also made of carbon fiber, but the light, stiff hull structure, daggerboard, and rudder are built using less-costly E-glass and Divinycell foam. Wetas key to fabrication success stems from the builders aerospace-like attention to detail. Vacuum-bagging and strict resin control results in the elimination of resin puddling and sloppy glasswork in hard-to-get-at areas, and offers excellent weight control. The 220-pound boat is as lean and fat free as a long-distance runner, yet retains the strength and stiffness needed in a high-performance sailboat. These boats are built in China, and they represent a new trend in Asian boatbuilding, an industry once known only for thick, resin-rich laminates and carved teak trailboards.

The deck layout and hardware selection make absolute sense, and show the value of continual input from accomplished small-boat sailors. Not only is there sensible layout of the sheet leads, cleats, and control lines, but all the gear works from either inboard or outboard hiking locations. When you first climb aboard the trimaran, youll find that theres plenty of room for two seated on the comfortable side deck of the main hull, and theres even room for big feet and the mainsheet tail in the full-length cockpit well. Sitting out to windward on the canvas trampoline, the tiller extension and sheet leads make sail trimming and screacher control a snap. Its hard to make a small boat really roomy, but the Wetas wide canvas side deck extension and main hull create plenty of room for a couple and a cooler.

The success of this pocket-sized trimaran also stems from its sailplan, a triple threat of main, jib, and easy-handling, furling screacher. The boomless mainsail, made by windsurfer sailmaker Gaastra, incorporates five full tubular battens that control draft and allow the mainsheet to be attached to a well-reinforced clew rather than a conventional boom. Its sculpted foot allows a crew to easily duck under during tacks but still keeps sail area maximized. Gaastra transferred quite a bit of its “go fast” sail shaping into the sailplan, including light tubular batten technology and X-ply and monofilm sail material. The high-tech Gaastra sail package, like the Harken hardware and carbon sprit and mast are all standard, and the result is a package primed for performance.

The upwind sailplan is that of a classic multihull with a big main (75 square feet) and small jib (23 square feet) providing enough drive to make ghosting in light air more than a possibility. Thanks to this efficient sailplan, tight sheeting angle, and a foil-shaped daggerboard, the boat points quite well-more like a one-design dinghy than a multihull. Steer a little wider and the roller furled “screacher” can add a virtual turbo boost. This 60-square-foot gennaker deploys like any roller furler but is trimmed via a single sheet led through both port and starboard leads. As a result, there is much less line to cope with and no sheet tails to drag in the water. To date, the top recorded speed has been 16.5 knots.

The ride is both exhilarating and responsive, sort of like sit-down windsurfing, lots of speed but fewer gymnastics. The helm is fingertip light, and the boats responsiveness takes a little getting used to in order to avoid oversteering. The slight up angle of the amas keeps the windward ama out of the water most of the time, reducing drag. Spray flies, and the boats proximity to the waters surface delivers an enhanced sensation of speed. In a way, it makes sailing more of a contact sport, best suited for warm water and sunny skies. Extending the sailing season means a commitment to good drysuit or wetsuit technology.

Putting the boat away is expedited by the handy beach dolly that comes as a standard component of the new boat. It captures the main hull and locks it in place for quick de-rigging or beach storage. It also eliminates the tendency to scar the hulls by dragging them up and down the beach. Rigging, and its end-of-session reversal, takes less than 20 minutes. This includes assembling the amas and hull, stepping the mast and sprit, and setting the sails. The boats user-friendliness is a tribute to the designers. Whether or not you enjoy multihull sailing, its hard not to give high marks to a well-thought-out sailboat.

One sold for $11500.00 with new paint job. The others sold between $8000.00-$9000.00. This boat is ready to sail with many upgrades and $9,000 value, asking $7,500. Or Best Offer. Resent Question answerThere is not a Fulmar 19 forum per se but there is quite a bit of information on other multi-hull forums if you Google Fulmar 19. There are also some Youtube videos showing the boat under sail. These boats were built by one of the biggest, trimaran boat builders in Canada. The boat was too expensive to manufacture; so they stopped production in 1998. As far as parts availability; this boat needs nothing at this point. All the hardware used on this boat is readily available at any marine, sailing company. As far as the sail goes--they were custom made for the boat and can be easily reproduced by any sail maker.Also, the Hobie Tandem Island trimaran sail would be a direct replacement and available from any Hobie dealer.This is probably one of the easiest boats to learn to sail and has great performance. One of the greatest features is the deployable sea-leg drive. If the wind dies, you just lower the drive and pedal t three or four knots.

Condor 40 Ocean Racing Trimaran Sailboat

Boca Raton, Florida

40' Condor Racing Trimarin. Built in 1988, this vessel sat way up the Miami River for 10 years, so it's had very little use. Extremely fast, very strong and stable. Great sails and equipment. Main, 110% Genoa (on roller-furler), Spinnaker Twin 4-Stroke 9.9 outboards with lift-brackets mounted on custom aluminum transom, Custom aluminum radar arch on stern, custom Edison wheel and pedestal with fixed rudder - (original kick-up rudder included), Stainless Steel Dodger, auto-pilot, GPS, VHF, some new rigging with Sta-Lok fittings, new main and spare halyards and other new lines. Self Tailing Winches, New canvas and oak below, porta-potti. Slab Reefing, Lazy Jacks, Stax-Packer, 2 Stainless Anchor mounts, All lines lead to cockpit for Cockpit Control, Boom Vang, Preventers, etc. 2 large hatches replace the original small inspection ports in each Ama (4 hatches - 2 in each hull) - making huge interior storage space in each hull - These hatches are large enough to allow a sailor to get down below into each Ama. The original hulls did not have this option. You can store sails, fenders, lines, fuel, etc in this space, allowing more room in the main hull for your personal equipment. This feature turns this racing machine into a comfortable cruiser. This is a Thoroughbred racing machine. Condors were built to OSTAR standard.,They are Blue-Water race tough, using top-of-the line materials like E and Bi-axial glass; and built to last. Also, vinylester resin was used throughout, which has kept Condors from suffering blistering issues. I have seen 6-8 foot waves break over this boat while sailing to windward and did not hear any creaking. This boat was built for short-handed trans-Atlantic racing. Clear Title in hand. The Captain of this vessel raced with Jack Petith (winner of the '84 OSTAR and '82 Route du Rhuum) This vessel is listed on Craigslist South Florida and Sailboatlistings.com so may be sold locally.

Category Cruiser Boats

Aquarius is easy to single hand, is great for day sailing yet sleeps five to six in four bunks (two in the fore-peak, one to two amidships, one on either side of the engine bay that has drop down sides for engine access). She's great for either a beginner or a seasoned sailor. O'Days are very popular, often raced, and there are several internet sites with information, forums and and offering of parts. I've had the pleasure of owning Aquarius for ten years now and I love her. We're relocating and after much procrastinating I realize that the ocean will just be too far way. The previous owners had her in Oyster Bay NY for many years. She is surprisingly fast yet very stable (2,230 lb lead keel) - although not suggested, we've powered through 6'-8' seas with her. She sails very close to the wind, is roomy with loads of storage, and you can stretch out on the 6'-6" cockpit seats with custom cushions (both with lockers beneath) or seat several. There's approximately 6' headroom. She has a 30 horse power Universal Atomic Four engine whereas most boats her size have either 9.9 HP outboards (which cavitate in lumpy water) or 7 to 13 HP diesels. She starts fast, runs clean. Uses about a gallon an hour. These are so popular that new parts are still made for it - even an optional hand crank! Here's one major source of new parts, service and info: moyermarine.com. She has a new jacket side plate from Moyer Marine. There's incredibly easy access to the engine from both sides and the front. There's even an engine "room" light. She has the original 12 gallon main gas tank along with the then optional 6 gallon plastic auxiliary tank (located on a shelf in the port side locker). Aquarius was made just before the cost of oil, gas and related resins sky-rocketed and caused many boat companies to skimp on construction and then to go out of business. Her hull is solid fiberglass - no balsa to worry about, and is about 3/8" thick. The prop is bronze. The prop shaft is bronze with a recent sacrificial zinc. I consider her the best year - 1975 had the best interior layout and has a lead ballasted fin keel with skeg mounted rudder (offering some protection to it). She has a 4' draft and nice freeboard which allows for usually dry sailing and calm guests.. My son worked at West Marine during school which gave us great discounts - she has new lifelines, new lazy jacks on the main boom, new main-sheet, new bronze thru-hull valves and Y-valve for the macerator toilet, new VHF radio, solar powered charger to keep her batteries charged between use, original Loran C, new coil and ignition parts, new water pump impeller, new engine exhaust pipe to the water muffler, new rubber diaphragm on her bilge pump, a cockpit tent in almost new shape, recent 12 volt receptacle, dual batteries with selector and gauge, tiller steering with nice looking new laminated wood tiller, old auto tiller, dual cockpit scuppers, cockpit cushions, anchor, teak and stainless steel swim ladder between the split stainless steel rear pulpit, auto-tiller, loads of storage, two sinks, cabin lights, electric macerator toilet between the fore peak and the main cabin with folding teak doors for privacy, curtains, cabin inclinometer, hanging locker, cockpit "table" (portable, that spans across the seats), storage under all the berths, a 12v hand vacuum, carpeting, a large ice box under a lid in the counter that drains to outside, alcohol stove plus a propane grill that attaches to hang off of the stern. There's a GPS/Depth sounder along with the original one that still works by a light revolving within its face and is entertaining to watch. There's roller furling, a wind vane and radio aerial atop the mast, stainless bow pulpit, a boom vang, a whisker pole for downwind sailing, genoa in reasonable shape, two jibs (one is older and a bit soiled), two mainsails (one also is older and a bit soiled). Two new stainless fishing rod holders, I've several life jackets, am/fm/cd stereo, full safety equipment including fire extinguishers, radar reflector ball, first aide kit, floodlight, Lifesling overboard rescue system, a flare gun, horn, boat hook etc. I can throw in a new medium sized dog life jacket if the buyer needs it. The upholstery is in very good condition. Loads of interior teak in good condition. The former owner gave us the original set of plastic dishes, silverware and ice tongs, and I'll give them to the new owner so they can stay with the boat. What I'm aware of: minor scars from dock battles etc, and a couple of soft deck spots which I was planning on repairing this season. The hardware & connections to the hull have been resealed over the years and should be checked. We had a problem with gunk in the main tank so we had it drained and we were planning on replacing it. We've been running off of the 6 gallon tank which has given us more than enough range. The sink hand pumps aren't working but I've a new electric pump to pressurize the system waiting to be installed (Whale offers refurbishment kits if you'd rather hand pump). The hatch boards are ready for replacement, last year there was minor weeping at the toilet - it may need tightening or a new gasket, and there's some minor rust here and there on the engine. Very little rain water weeps in from the ports - I do a yearly sealing but this year haven't gotten to it yet. She's a pretty dry boat. Aquarius has loads of spare parts including a new small holding tank for the toilet, new deck hardware along with a good-sized used winch for the cabin top to make single handling even easier, new electric water pump to pressurize the water system, new electric bilge pump - all ready to be installed. Obviously I love the boat - we weren't planning on moving from Brooklyn but the house that we've bought was an amazing deal in a historic small town and we realized that's where we want to semi-retire. She's out of the water in Gateway Marina (opposite Floyd Bennett Field) in Brooklyn open to the bay and to the ocean. The marina owes us a launch but it seemed to make sense to allow prospective buyers a look at her bottom. Here's more info: oday.sailboatowners.com, odayowners.com and iheartodays.com/model_oday_27 There was an ad in Craigslist for her but it was put in without my knowledge by a marina service employee. It was taken off. The boat is sold as is, and will need to be picked up or sailed from her location in Gateway Marina, Brooklyn, NY by the new owner. Storage and shipping arrangements are the responsibility of the purchaser. You may see the boat by appointment. She is fairly priced - serious offers only please.

Russian IADS Redux Part-7: The Effectors

In the next part of our series on Russia’s strategic integrated air defence system, we look at the kinetic ground-based air defence systems it deploys.

In part-6 of our series on Russia’s strategic Integrated Air Defence System (IADS) we examined the command and control architecture it depends upon. The IADS’ role is ultimately to provide a response to air threats approaching or entering Russian airspace. In Russian air defence doctrine this response is provided using kinetic and/or electronic effects.

The kinetic side of the IADS depends on the Russian Aerospace Force’s (RASF’s) fighters and Surface-to-Air Missile (SAM) systems. Sources have shared with Armada that both the fighter and SAM force would be deployed in wartime to protect key Russian strategic targets. Typically, these could include politico-military targets like the Kremlin, the seat of the Russian government in Moscow. Other potential strategic targets include hardened facilities believed to be earmarked for use by the Russian leadership in wartime. One of these facilities is thought to be located at Mount Yamantau, southwest Russia. A back-up facility may exist at Mount Kosvinsky Kaman, western Russia. Russia’s industrial city of Elektrostal, on the eastern outskirts of Moscow, was one of the first locations where the RASF deployed its S-400 (NATO reporting name SA-21 Growler) high-altitude, long-range SAM systems in 2010.

The SAM Systems

Moscow itself is ring-fenced by the RASF’s 53T6 (ABM-3 Gazelle) anti-ballistic missile system. The 53T6 employs SAMs equipped with a ten kiloton (one kiloton is equal to 1,000 tonnes of conventional explosive) nuclear warhead. These missiles would detonate at altitude in proximity to incoming salvos of ballistic missile warheads or formations of hostile aircraft. The logic is that this ‘shotgun’ approach will vaporise, or at least badly damage, these targets.

The S-400 is the mainstay of the RASF SAM force. A typical S-400 battalion includes two batteries. A battery comprises between eight and twelve individual launch vehicles, each equipped with four missile tubes. Thus, an S-400 regiment could have between 56 and 84 individual missiles ready to launch if fully loaded.  Each battery has a command post, a 91N6 (Big Bird) S-band (2.3 gigahertz/GHz to 2.5GHz/2.7GHz to 3.7GHz) 324 nautical mile/nm (600 kilometre/km) range surveillance and tracking radar. The 91N6 is joined by a 96L6E (Cheese Board) C-band (5.25GHz to 5.925GHz) early warning and target acquisition radar. This radar has a range of up to 162nm (300km). A plethora of SAMs can be launched by the S-400 with an array of engagement ranges from 21.6nm (40km) using the active radar homing 9M96E missile. Engagement ranges can reach up to 216nm (400km) using the 40N6E missile which has a reported engagement altitude of 98,425 feet/ft (30,000 metres/m).

Legacy systems used by the RASF include the S-300PS (SA-10B Grumble-B) and S-300PM (SA-10D/E Grumble) which have subtle differences. An S-300PS battery has three Maz-543 launch vehicles each with four launch tubes. The battery is also equipped with a single 5N63S (Flap Lid-B) X-band (8.5GHz to 10.68GHz) fire control radar. An S-300PM battery has a single 36N6E (Flap Lid) X-band/Ku-band (13.4GHz to 14GHz/15.7GHz to 17.7GHz) fire control radar with a 162nm (300km) range. Joining the 36N6E is a 76N6 (Clam Shell) X-band (8.5GHz to 10.68GHz) search and track radar with a 70nm (120km) range. The rest of the battery is comprised of up to eight Kraz-260 launch vehicles each with four tubes. Both the S-300PS/PM are thought to deploy 48N6/E SAMs which have a reported 81nm (150km) range. The S-300PS/PM’s 5V55R missile has an engagement range of up to 48.6nm (90km).

Sources have shared with Armada that RASF SAM batteries are not routinely deployed but may deploy from time-to-time to support exercises or training. The batteries would only be deployed in anger to protect key strategic targets like those discussed above. The sources continued that the task of the SAM units is to provide a protective ‘bubble’ above these targets. Air defence coverage up to 54 nautical miles/nm (100 kilometres/km) altitude and a range radius of 189nm (350km) around the target would be provided. The SAM units would work to attrit any incoming air attack as much as possible. Russian air defence doctrine focuses on safeguarding as many strategic targets as possible in anticipation of an eventual counterattack.

One crucial part of the RASF’s SAM force is its 96K6 Pantsir-S1 (SA-22 Greyhound) combined medium-range SAM and anti-aircraft artillery systems. 96K6 units would deploy with S-300 and S-400 batteries. Their role would be to destroy air-launched weapons like anti-radiation missiles or attack helicopters engaging the batteries Armada’s sources added.

Over the longer term, the RASF is looking to introduce new SAM systems to enhance the strategic IADS in the form of the S-350E and S-500 Prometey long-range, high-altitude SAM systems. The S-350E is mooted as a replacement for the RASF’s S-300PS/PM batteries. Open sources state that a S-350E battery has one 50N6A X-band ground-based air surveillance radar with a range of 215nm (400km). The 50N6A is joined by a single 50K6A mobile command post and up to eight 50P6 launch vehicles. Each launch vehicle can fire 9M96/E or 9M100 SAMs with engagement ranges and altitudes of up to 65nm (120km) and 98,000ft (30,000m) respectively. It was reported in January 2020 that the first S-350E battery had entered service, although a developmental system may have been deployed to support Russia’s military presence in Syria. The VKS could receive twelve S-350E batteries by 2027.

The S-500 is mooted to have a longer engagement range than the S-350E. The S-500 ensemble includes a 91N6A(M) air surveillance and battle management radar. This radar is an enhanced version of the 91N6A radar accompanying the S-400. The S-500’s 96L6TSP target acquisition radar is an enhanced variant of the S-400’s 96L6E. These two systems are accompanied by the 76T6 multimode fire control radar, itself thought to be a derivative of the 92N6. Also forming part of the S-500 ensemble is the 77T6 anti-ballistic missile engagement radar the capabilities of which remain largely unknown in the public domain.

Open sources say that missiles equipping the S-500 could hit targets at ranges of up to 270nm (500km). Russian sources have claimed that the S-500 could engage targets at up to 656,168ft (200,000m) altitude. Russian media, seldom the most reliable source, claim that the first S-500 regiment went on combat duty in October 2021.

The long-term prognosis for the S-500 and S-350E systems remains uncertain. As documented by the Royal United Services Institute, a London-based thinktank, the Russian defence industry is dependent on clandestinely-sourced Western microelectronics for sophisticated weapons systems. Will Western efforts to clamp down on Russia’s access to such technology have an impact on the fortunes of the S-350E and S-500?

Stay tuned for more analysis on Russia’s strategic air defence capabilities in the next instalment of our Russian IADS Redux series.

Title : Active carbons as nanoporous materials for solving of environmental problems

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of  such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds.  Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

Victor M. Mukhin was born in 1946 in the town of Orsk, Russia. In 1970 he graduated the Technological Institute in Leningrad. Victor M. Mukhin was directed to work to the scientific-industrial organization "Neorganika" (Elektrostal, Moscow region) where he is working during 47 years, at present as the head of the laboratory of carbon sorbents.     Victor M. Mukhin defended a Ph. D. thesis and a doctoral thesis at the Mendeleev University of Chemical Technology of Russia (in 1979 and 1997 accordingly). Professor of Mendeleev University of Chemical Technology of Russia. Scientific interests: production, investigation and application of active carbons, technological and ecological carbon-adsorptive processes, environmental protection, production of ecologically clean food.

WGS 84 coordinate reference system is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS satellite navigation system (the Global Positioning System).

Geographic coordinates (latitude and longitude) define a position on the Earth’s surface. Coordinates are angular units. The canonical form of latitude and longitude representation uses degrees (°), minutes (′), and seconds (″). GPS systems widely use coordinates in degrees and decimal minutes, or in decimal degrees.

Latitude varies from −90° to 90°. The latitude of the Equator is 0°; the latitude of the South Pole is −90°; the latitude of the North Pole is 90°. Positive latitude values correspond to the geographic locations north of the Equator (abbrev. N). Negative latitude values correspond to the geographic locations south of the Equator (abbrev. S).

Longitude is counted from the prime meridian ( IERS Reference Meridian for WGS 84) and varies from −180° to 180°. Positive longitude values correspond to the geographic locations east of the prime meridian (abbrev. E). Negative longitude values correspond to the geographic locations west of the prime meridian (abbrev. W).

UTM or Universal Transverse Mercator coordinate system divides the Earth’s surface into 60 longitudinal zones. The coordinates of a location within each zone are defined as a planar coordinate pair related to the intersection of the equator and the zone’s central meridian, and measured in meters.

Elevation above sea level is a measure of a geographic location’s height. We are using the global digital elevation model GTOPO30 .
