Hull

The hull 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 227.0 liter fresh water capacity.

Rig

The Gemini 105Mc 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

CentreBoard

The Gemini 105Mc is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can enter even shallow marinas as the draft is just about 0.46 - 0.56 meter (1.51 - 1.81 ft) dependent on the load.

Engine

Gemini 105Mc may be equipped with an inboard Westerbeke diesel engine at 27 hp (20 kW).

The fuel tank has a capacity of 136.0 liters (35 US gallons, 29 imperial gallons).
