reinforcement around the edges, and are covered with glassfibre
cloth applied with epoxy resin

polystyrene
construction of a jig to
support construction of the hull
panels added to provide a
surface on which to build up the foam core
completed central plywood
stringer, with rudder mounts at the back, centreboard box, a
vertical tube for optional windsurfing rig, and a horizontal
tube at the front end for optional bowsprit

initial shaping of
centreline ridge
foam fillet added between
the ridge and underside
two layers of glassfibre
cloth laid on with epoxy resin
