For anybody thats interested the plans are available from;
They're built from flat carbon panels. Panels are taped and epoxy filleted together. Quite simple for one boat, but if I was to do it again I'd probably build a plywood plug and layup carbon over it. I made my own keel and rudder molds. They were intended to be 'cheapies'. I've used mast/gooseneck stubs (one set up for all rigs) to save money.
Plans come with a raised fore deck but to keep it simple I used flat decks. All up with 3 rigs (sails from Housemartin - England) RMG winches etc they have cost around $1000 each.
Should be good fun sailing them - Australian Nationals in January 2013
