The Skoota 18 is a simple to build and trail powercatamaran. It is based on the Chat 18 sailing catamaran but with extra buoyancy aft to take a bigger engine, up to 20hp. This gives an economic cruising speed around 9-10 knots and top speed in the low teens.
The small cuddy offers protection during the day while the boom tent and long cockpit seats mean you can camp on board for a night afloat
The boat is built using conventional stitch and glue plywood, build time is estimated at 300 hours. Please email me for more details and basic studypack.
This website http://projectcatamaranchat18.blogspot.co.uk/ shows the build of a Chat 18 which is very similar to the Skoota 18, the latter has no keels and a slightly different hull shape making it more suitable for a powerboat
