Sorry, no cost estimate. It is cheap to build the hulls though. Spruce planks ripped into ribs. Some light glass and more epoxy than you think. We did 12 half hull panels so the cost have to be split on 3 boats.
Real cost is in fittings, foils, rig and sails.

Designer is a personal friend and supplied scantlings. This is a one off and there will be no more scantlings from him, at least that was what I heard back then. Designer is currently building a Farrier tri so he is busy. If I am going to build other boats it will not be in strip plank. Go for plywood if you want a fast build.
I do happen to have 4 extra hull panels in storage though, after a partner pulling out of the build..
