Thanks everyone, I was expecting the rig sails, and foils to cost the most. It's a little scary when you add it all up.
If I decide to build, does anyone in Australia have a deck jig they've finished using?
To complicate things further I only have a single car garage, i've built a 13ft monohull in there, so I might have to do one hull at a time. At least until the stage it can be stored undercover outside.
Regards, Chris.
