Personally, I'd go with aluminum but wood may be simpler if you can find
a good grade of light, straight, clear grained lumber (spruce is ideal).

You don't describe the geometry of the sail, or the rigging. Is the sail
triangular or four sided? If the sail is hoisted on the mast without a
boom, how is the sheet rigged? What happens when you pull it in tight?

A couple of boat plans I had purchased over the years (but never used)
suggested going to a farm irigation supply company for the aluminum
tubeing for mast/boom. Should be much cheaper.
