The ETAP 30cq is a Belgian sailboat that was designed by Marc-Oliver von Ahlen as a cruiser and first built in 2010.
The construction is of a polyester glassfibre and closed-cell polyurethane foam sandwich, which provides buoyancy and makes the boat unsinkable.
It has a 7/8 fractional sloop rig, a plumb stem, a walk-through reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel or optional dual tandem keels.
[1] The boat is fitted with a Swedish Volvo Penta D1-20 diesel engine of 19 hp (14 kW) for docking and manoeuvring.
[7][8][9] The boat was at one time supported by a class club, the ETAP Owners Association.
