Gato,
While I think commercial construction has to be a primary objective to get them out there in numbers I agree regarding you rcomments on home building.
I hope to provide plans that detail the construction in ply, foam and cedar strip depending on an individual's preference as well as detailed instructions on making the sail. The only marine fittings will be a couple of blocks. Everything else will be obtainable form a timber yard and hardware type store.
Regards,
Phill
