The hull 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 boat is equipped with 2 berths and a galley.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.
Unknown keel type
Besst 505 can enter even shallow marinas as the draft is just about 0.58 - 0.68 meter (1.90 - 2.20 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Yanmar 1GM diesel engine at 8 hp (5 kW). Cruise speed is 5.0 knots.
The transmission is a shaft drive. A shaft drive will in the long run require less maintenance 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 Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 5.2 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 Besst 505 is about 61 kg/cm, alternatively 345 lbs/inch.
Meaning: if you load 61 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 345 lbs cargo on the boat it will sink 1 inch.

Curiosities
In Denmark, you are required to have achieved a 'powerboat driving license' in order to sail a powerboat.
In this context a boat is considered a powerboat if:
Danish definition of a powerboat
Though, if you install a motor of 28 kW (38 hp), then the boat will become a powerboat, and you will need a Danish 'powerboat driving license'
