ECO 6: A catamaran for a self-builder

The stated objective is to have a proper cruising boat at a low price - the cost of materials for the hull shouldn’t exceed €4,000, then count on another 3,500 for deck fittings, interior and installing a full rig, and buying yourself a small outboard. The extra 50 cm (18”) compared to the ECO 5.5 provides more living space - thanks to the raised deck, something surprising for a catamaran only 2.84 m (9’4”) in beam. There is a saloon that can be converted into a double berth – positioned athwartships -, a galley in the starboard hull and a single berth - accompanied by a heads compartment (with a door!). The maximum headroom is 1.64 m (5’5”) at the entrance into the nacelle. The architect is proposing two different sail plans: traditional sloop or gunter-rigged.
