Tom,
The blades are steel T sections attached to laminated wood runners. The
mast is also laminated of various types of wood. The sail bolt rope
attaches to the mast and boom thru the groove in the mast and boom just
like modern aluminum masts and booms. I do not know how to tell if the
plywood is formed or layed-up veneer. I'll look for some more
identification this weekend. The sail was made in Toronto Canada and
the battens are solid wood. Thanks for information. Dave
