Jupiter 30 is a 29 ′ 3 ″ / 8.9 m monohull sailboat designed by E. G. Van de Stadt and built by Jupiter Yachts starting in 1982.

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)

Review of Jupiter 30 (S)

Basic specs..

The boat is typically equipped with an inboard diesel engine at 11.0 hp (8 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Jupiter 30 (S) is 2.23, indicating that this boat would not be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Jupiter 30 (S) is about 193 kg/cm, alternatively 1086 lbs/inch. Meaning: if you load 193 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1086 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is L/B (Length Beam Ratio)?

SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 23.91

Jupiter 30 HFS Boat Review

Home » Boating Blog » Reviews » Jupiter 30 HFS Boat Review

Jupiter 30 HFS Boats

Fun and versatility from every angle.

Not all boats are made to be multi-taskers and that is truly a shame. With many boat brands it takes many boats just to have all of the boater’s needs fulfilled. The Jupiter brand is known for producing some of the best fishing boats on the market today, but they also design boats that do much more than simply fish. If you are in the market for one boat to do it all. The Jupiter 30 HFS boats for sale are the ones to seek out.

Power and Performance

A boat cannot merely look good sitting on the water. It has to be more than just a pretty face. The Jupiter 30 HFS boats for sale are truly beautiful boats with multiple color options, but what is more important to boaters is the speed of the vessel. The twin engine configuration is optimal for this boat. Although Jupiter allows for many different motor choices for thee 600 HP rating, the standard choice maximizes the horsepower rating with two Yamaha 300s blasting the bot through the water. The speed of the engines combined with the maximum strength of the hull, the Jupiter 30 HFS will take you anywhere you want to be on the water.

Maxed Out Fishability

The Jupiter 30 HFS boat is equipped with everything the avid fisherman needs for an excellent day out on the water. The transom of the vessel offers a substantial fish box along with a convenient prep station with live bait well. The bow offers two additional fish boxes to keep everything fresh throughout the day and when it is time to head back for the day or store the rods while in port, the lockable rod lockers, both port and starboard offer ample space for all of the fishing rods tucked away nice and neat under the deck. Additional rod holders are found on either side of the boat as well as at the bait prep station, so no matter where you happen to be, you will have the fishability to maximize the journey.

Convenient Features

For family outings, fishing gear might not be that important to everyone, but what will be very important is the convenience and comfort of the vessel. These two aspects go hand in hand when talking about getting out on the water with the family and when it is time to take care of personal business, the expansive head compartment does the job. Most center console boat head compartments are quite cramped, but onboard the Jupiter 30 HFS, the head compartment is large enough for a 6’ adult to enter and move around easily. The access to the electrical components of the center console is in this area as well. When the boat is not being used or in port, this space can be locked for storing any valuables or for additional rod storage.

For an added bonus for the convenience of the family, the center console seating area is not merely comfortable, but functional as well. The seat cover lifts to reveal a cooler for drinks and snacks. The wrap around bow seating area is also another convenient area with versatility. Whether using it for standard seating or twin loungers, the space is comfortable and convenient on any excursion.

30-day dry time proposed for Yellowstone-bound boats

To reduce the possibility of invasive mussels reaching Yellowstone Lake, the National Park Service is considering a requirement that a boat be inspected and sealed to its trailer for 30 days ahead of its intended launch date.

The requirement, if adopted, would apply to all inboard/outboard and inboard jet motorboats and sailboats. The Park Service referred to such craft as complex motorized boats. An exception would apply to boats powered only by an outboard motor.

“Large, complex, trailered watercraft pose the highest risk of transporting and introducing invasive mussels, and other AIS, because they are difficult to inspect and less likely to completely drain/dry or be fully decontaminated,” the Park Service wrote. “Manual decontamination with the use of hot water is not always 100% effective in removing all mussels. Given this, a 30-day dry time is needed to mitigate the risk associated with these watercraft.”

In addition, the Park Service is proposing to “deny launch to any watercraft (motorized or non-motorized) that has previously been fouled by mussels, regardless of dry time.”

In seeking public comment through April 5 on the proposal, the Park Service cited the “increased risk of invasion” by zebra and quagga mussels, collectively referred to as dreissenid mussels, “following recent detections of these highly invasive species in waterways” close to the park.

The mussels “have caused irreversible ecological damage and extensive impacts to infrastructure and recreation in waterways throughout the Midwestern and Eastern United States, as well as in the lower Colorado River Basin,” the Park Service noted.

New infestations were detected in South Dakota’s Pactola Reservoir in 2022 and the Snake River near Twin Falls, Idaho, in 2023. The Idaho detection was the first time the mussels had made it into the Columbia River Basin.

In addition, during inspections last year and in 2022, Yellowstone officials “intercepted and denied launch to mussel-fouled watercraft, highlighting the urgency and severity of the threat.”

“Given Yellowstone National Park is located at the headwaters of the Yellowstone, Snake, and Missouri river drainages, pro-active measures are required to ensure the long-term ecological integrity not just of Park waters, but also of downstream mussel-free waters in Wyoming, Montana and Idaho,” the Park Service wrote. “Failure to prevent invasion by dreissenid mussels could result in widespread negative impacts to natural resources and recreational values, and could undo over two decades of work to restore populations of native Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri) within the Park. Because there are no effective eradication methods, and control/containment is both costly and environmentally consequential, prevention of an introduction is critical.”

Seals from Yellowstone National Park, Idaho State Department of Agriculture; Montana Fish, Wildlife, and Parks; and Wyoming Game & Fish Department will be honored pending verification of the 30-day dry time during an already-mandatory Yellowstone AIS inspection prior to launch. Boaters will also be asked to present the inspection receipt from the date the seal was applied.

The preferred method for submitting comments is online at https://parkplanning.nps.gov/yellboats. Comments may also be mailed to: Yellowstone Center for Resources Attn: AIS Proposed Changes, PO Box 168, Yellowstone National Park, WY 82190. The deadline to submit comments is Friday, April 5.

At the conclusion of the 30-day public comment period, the NPS will analyze and consider all comments received.

A final decision is expected this spring.
