Review of Mamba 370

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

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 4 cabins, 8 berths, a galley, toilet facility and 60 liter waste water capacity.

The boat 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 genaker or a spinnaker for optimal speed.

The boat is typically equipped with an inboard Volvo Penta MD2030 diesel engine at 28.0 hp (20 kW), which gives a max speed about 6.0 knots.

The fuel tank has a capacity of 80 liters (21 US gallons, 17 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Mamba 370 is 1.79, 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 7.5 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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Mamba 370 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.
