Review of M 22

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.

An outboard motor is often used on this boat. In that case the boat will typically require a power of 3 - 4 hp, alternatively 66 - 80 lbs thrust if you prefer an electrical motor. Electric outboards are becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.

What is Capsize Screening Formula (CSF)?

The capsize screening value for M 22 is 1.59, 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 6.0 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 M 22 is about 73 kg/cm, alternatively 411 lbs/inch.
Meaning: if you load 73 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 411 lbs cargo on the boat it will sink 1 inch.
