The ECO 7.5 is the logical bigger version of the ECO 5.5. But it is a total different boat. The hulls are multi chine designs.
For dimensions, see the specifications. The layout speaks for itself. The boat has proven to be a perfect boat for long distance cruising. The boat has proven to be a very good coastal cruiser.
Construction and design. Like all our designs, the boat is a (ply-)wood/glass /Epoxy construction.
The headroom in the hulls is 1.92 to 1.82m, where it counts.
Big storage areas (inside and outside) makes the boat a perfect boat for extended vacations.
The plans show two sail plans. The first is a conventional fractional rig. The wishbone gaff rig has a roller reefing jackstay for fast main sail operation (see next page). Engine choices, two outboard engines, each with about 5 HP, or a single center-mounted outboard.
