Hull

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.

Engine

The boat is typically equipped with an inboard Yanmar diesel engine at 22.0 hp (16 kW), which gives a max speed about 5.3 knots.

The fuel tank has a capacity of 102 liters (26 US gallons, 22 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 Morgan 32 Mk III is 2.07, indicating that this boat would not 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 6.7 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 Morgan 32 Mk III is about 179 kg/cm, alternatively 1003 lbs/inch.
Meaning: if you load 179 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1003 lbs cargo on the boat it will sink 1 inch.
