Hull

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

Interior

The boat is equipped with 1893.0 liter fresh water capacity.

Rig

The Catalac 11M is 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

Bilge keel

The Catalac 11M is equipped with a bilge keel. A bilge keel is a double 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 0.84 - 0.94 meter (2.76 - 3.06 ft) dependent on the load.

Engine

Catalac 11M may be equipped with dual inboard Yanmar 2GM20 diesel engines at 18 hp (13 kW).

The fuel tank has a capacity of 832.0 liters (219 US gallons, 183 imperial gallons).
