Review of Scanmar 40

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.
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.

The boat is equipped with 6 berths and a galley.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The boat is typically equipped with a Volvo Penta engine.

The fuel tank has a capacity of 150 liters (39 US gallons, 32 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Scanmar 40 is 1.98, indicating that this boat could - if evaluated by this formula alone - 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 7.8 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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Scanmar 40 is about 268 kg/cm, alternatively 1502 lbs/inch.
Meaning: if you load 268 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1502 lbs cargo on the boat it will sink 1 inch.
