Hull

Both the hull and the deck is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
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 deck is a double deck which improves the indoor climate.


Interior

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 0 cabins, 7 berths, a galley, 120.0 liter fresh water capacity and toilet facility.

Rig

The Compis 36 is 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 gennaker or a spinnaker for optimal speed.


Keel

Fin keel

The Compis 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.

The boat can enter most marinas as the draft is just about 1.78 - 1.88 meter (5.84 - 6.14 ft) dependent on the load. See immersion rate below.


Engine

Compis 36 may be equipped with an inboard Yanmar 3GM diesel engine at 22 hp (16 kW). The speed is 8.0 knots.

The transmission is a saildrive.

The fuel tank, which is made of stainless steel, has a capacity of 40.0 liters (10 US gallons, 8 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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Compis 36 is 1.83, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.5 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.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Compis 36 is about 204 kg/cm, alternatively 1147 lbs/inch.
Meaning: if you load 204 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1147 lbs cargo on the boat it will sink 1 inch.

What is Relative Speed Performance?

The Relative Speed Performance for Compis 36 is 66

Slow Fast 66% 0 50 100
The relative speed performance is 66 which means that a it is faster than 66% of all similar sailboat designs.


Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 36m2 (387 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
