Ravage 36 is a 36 ′ 6 ″ / 11.1 m monohull sailboat designed by Niels Jeppesen and built by Bianca Yachts starting in 1979.

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 Ravage 36

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well. The boat is equipped with 8 berths, a galley, 120.0 liter fresh water capacity and toilet facility. Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

The Ravage 36 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

Ravage 36 can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard engine at 10 hp (7 kW). Calculated max speed is about 4.0 knots

The transmission is a saildrive.

The fuel tank has a capacity of 60.0 liters (15 US gallons, 13 imperial gallons).

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 Ravage 36 is 2.02, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Ravage 36 is about 189 kg/cm, alternatively 1061 lbs/inch. Meaning: if you load 189 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1061 lbs cargo on the boat it will sink 1 inch.

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 33m 2 (355 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

The Ravage 36 is a 36.52ft fractional sloop designed by Niels Jeppesen and built in fiberglass by Bianca Yachts since 1979.

41 units have been built..

The Ravage 36 is a light sailboat which is a high performer. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a fast cruiser. There is a very short water supply range.

Ravage 36\' Anyone got an opinion on this class, any known problems, sailed one ?

Re: Ravage 36\' V popular in Denmark, country of origin. I met one once and the owner sung her praises (he would wouldn't he) as a good offshore boat. I think she has a (small?) skeg. When I looked round, she seemed well built and good fittings, such as cleats. Personally she looks v light for 36ft, but probably goes well in light airs (I didn't go out in her). Bald details, which you probably already have, can be found at here

“ I just received my asymmetrical spinnaker, with sock and turtle bag, along with a new 135 Genoa. The entire process was simple and both sales and the design team were in regular contact if there were any questions. The customer portal was easy to use and lets you keep track of where in the process your sails are. Great sails, great service -Graham Edwards (Facebook)

“ The whole team at Precision Sails was fantastic from start to finish. We’ve had a laminate main and genoa made so far and have a spinnaker on the way. They listened carefully to our needs and recommended a great sail cloth. We couldn’t have gotten more bang for our buck! -Noah Regelous (Google)

“ We received our spinnaker and launched it yesterday and I just wanted to let you know how pleased we are with it. The service we received from your company was exceptional and the quality of your product is second to none. We will certainly be return customers in the next few months to replace our main and jib sails and will recommend your company to all our sailing buddies. Once again-thank you.” -Daniel Jackson (Google)

“ we had good communication during the planning stages and the knowledgeable people at precision sails really got me fixed up good! The sails look and work fabulous! my boat sails better than it ever had! couldn’t be more pleased with the product AND the service!” -Fred Jelich (Facebook)

“ Our new furling jib for a Corsair 27 Had to be specially designed due to the height of the furler, but this was accomplished quickly and in short order we had our sail which fits beautifully and has a great shape. It’s everything we could have wanted, high tech design, thoughtfully executed and affordable.” -Nancy Y. (Yelp)
