After many requests for a bigger ECOnomy cruiser here she is. For dimensions see the specifications. The layout speaks for it self. This boat is a perfect boat for the whole family. It is designed for extended coastal cruising.

Construction and design: The ECO 7.5 is a multi chine design. Like all our designs the boat is of plywood/glass/Epoxy construction. The headroom in the hulls is from 1.92m to 1.82m where it counts. The seat height around the table is at least 98 cm. Big storage areas (inside and outside) make the boat a perfect one for extended vacations.

The plans show two sail options. The first is a conventional fractional rig. The secone, a wishbone gaff rig, has a roller reefing jackstay for fast main sail operation. Engine choices: two outboard engines, each with about 5 HP or a diesel electric drive with solar panel back up and/or trailing generator.
