13.80 METER ALUMINIUM CNC KIT SET SAILING CATAMARAN
DESIGNED BY ANGELO LAVRANOS

A lot of family cruising people like the superior space, better live aboard features, and excellent (trade wind) reaching performance of catamarans, but would like a more damage tolerant aluminium boat, as opposed to a relatively delicate GRP sandwich which is the norm. With careful design, it is possible to avoid increased weight and reduced performance, using aluminium, while still being compliant with classification society structural criteria.

Additionally this design can be assembled by a relatively inexpensive commercial aluminium fabricator, having simple conic "wrap-able" curvature, multi chine, using a complete CNC cut "kitset". This brings the cost quite close to that of a GRP production hull/deck. The hull form is similar to my successful smaller kit set "Proteus" design.

This boat represents the optimum point where the boat is big enough to be "light" even though built in aluminium, but small enough to be easily handled two up, as a family boat. She is also the minimum size for a true "live aboard" cruiser.

At present the design has a four cabin "charter" layout, but other layouts are possible. Also very shallow draft dagger boards are incorporated, but fixed mini keels is also an available alternative.
