Interior

The boat is equipped with 4 berths, a galley and toilet facility.

Rig

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.

Keel

The boat can enter even shallow marinas as the draft is just about 0.66 - 0.76 meter (2.17 - 2.47 ft) dependent on the load. See immersion rate below.

Engine

An outboard motor is often used on this boat. In that case Hardy 537 will typically require a power of 2 - 3 hp, alternatively 40 - 48 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.
