The ETAP 21i has a surprisingly long water line (6.10 metres) and a totally new hull designed by Mortain and Mavrikios in co-operation with ETAP. With a displacement of 1,180 kg (including a 300 kg keel), dual rudder controls and a full 24 m² of sail area, the ETAP 21i has great appeal for competitive sailors.

The ETAP 21i is a superb family sailing yacht too: its superbly designed internal layout offers sleeping accommodation for 4 people, a roomy main cabin, a functional corner galley and ample stowage space. The ETAP 21i is easy to tow and offers effortless launching straight from the trailer when fitted with the ETAP tandem keel.
