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 boat is equipped with 6-7 berths, a galley 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.

Engine

Comfort M35 is typically equipped with an inboard Volvo Penta AQD 40 diesel engine at 130.0 hp (96 kW).

The transmission is a shaft drive.

The fuel tank has a capacity of 480.0 liters (126 US gallons, 105 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.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.8 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 Comfort M35 is about 234 kg/cm, alternatively 1313 lbs/inch.
Meaning: if you load 234 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1313 lbs cargo on the boat it will sink 1 inch.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Comfort M35 is 3.29.

Compared with other similar motor boats it is slimmer than 69% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

Curiosities

Danish definition of a powerboat

According to this definition this boat is not categorized as a Powerboat.
Though, if you install a motor of 128 kW (172 hp), then the boat will become a powerboat, and you will need a Danish 'powerboat driving license'

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 37m² (398 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.
