The inside lay out with the enclosed bath room speaks for it self. In hulls have standing height. The height on the bridge deck saloon is  1,20m. Enough for comfortable seating on the settee. The boat is build from 8 and 6mm plywood over stringers. The construction manual describes an easy way for fairing. In the end this is the quickest way to build the boat. The whole boat is covered with fiber glass and painted with PU paint.

The plans consists of 20 drawings. The technical drawings are to scale 1 : 1. File format DXF. The 14 pages manual gives a description of the construction of the boat.

The ECO 75 power cat is the big brother of the ECO power cat. Designed along the same lines and with the same philosophy. Easy to build boat by an amateur. Construction is the time proven plywood/glass fiber/Epoxy composite system. Nothing can match this system for weight, costs and easy of construction. Besides this advantages no maintenance will be necessary over many years.
The hulls start with a deep V on the bow and a wide V at the transom. So the boat will be sea worthy. The hulls are designed for medium speed. Speed with a 25 HP engine will be around 25 knots full power and 18 knots at half power. So the boat will be very ECOnomical to run and maintain.
One attractive features is the front cockpit. This is not only a nice place for sun bathing but also a safe place for anchor maneuvers. The front hatch makes it not necessary to walk over the deck in a bad weather situation.
