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.


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 3 cabins, 8 berths, a galley, 275.0 liter fresh water capacity, toilet facility and 100.0 liter waste water capacity.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.


Rig

The Comfortina 38 Cr 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 Comfortina 38 Cr 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.

Comfortina 38 Cr can only enter major marinas as the draft is about 1.95 - 2.05 meter (6.40 - 6.70 ft) dependent on the load. See immersion rate below.


Engine

The boat may be equipped with an inboard Volvo Penta 2003 diesel engine at 28 hp (20 kW). The speed is 7.5 knots.

The transmission is a saildrive.

The fuel tank, which is made of stainless steel, has a capacity of 95.0 liters (25 US gallons, 20 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 Comfortina 38 Cr is 1.89, 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 Comfortina 38 Cr is about 222 kg/cm, alternatively 1247 lbs/inch.
Meaning: if you load 222 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1247 lbs cargo on the boat it will sink 1 inch.
