Scarab 32 trimaran

The Scarab 32 trimaran is Ray's latest design. We are building a prototype of this design using foam/polyester panels although the boat was designed to be built in plywood. We like building with chines because of the quick build and finish using this technique. We are using foam instead of plywood for a couple of reasons:

  • Half of the build team is extremely allergic to epoxy
  • The boat is lighter therefore faster
  • Reduces condensation inside the boat when left on a mooring
  • Higher resale value
We make full size panels by joining the foam together (this 32 foot boat is a 4 sheet boat) before we apply the glass. If we were using plywood we would scarf the panels before we cut them out so we would end up with the same panel before we attached it to the building frame. (See building the panels)
Ray’s design for this boat will include DXF cutting files for use with a CNC cutter when building the boat from plywood. These panels will have a key shape cut in the ends so the panels can click together and save scarfing.
On this build Ray is going to do all the construction work and fit-out while Fran will do all the laminating (beams and panels), finish and paint. This should avoid too many conflicts.
We have received many emails from people who like the idea of watching someone build a boat so we will include many pictures and building hints which we hope will interest you.
We started the boat on 1 November 2011 when we ordered material. The entries will be added like a blog as works progresses. I will keep you advised of our progress.
