Hull

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

Rig

The Hirondelle Mk III is built 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

Bilge keel

The Hirondelle Mk III is built with a bilge keel. A bilge keel is a twin keel, which allows the boat to be beached. Bilge keels are the most popular keel for tidal waters.

The boat can enter even shallow marinas as the draft is just about 0.76 - 0.86 meter (2.49 - 2.79 ft) dependent on the load.
