Normally, one uses a canvas 'boot'. It's essentially a truncated conic section. The geometry for the layout is fairly simple -- a little work with a compass, straight-edge and measuring tape ought to do you.

I am restoring a 1967 32' wooden yawl. The wooden mast is keel footed. Where the mast exits the cabin there was a bronze sleeve and probably some kind of boot attached to it. When I bought the boat rain water was kept out thru the use of duct tape. Seems like the hot setup would be to solid mount the mast where it exits the cabin roof so that I can make a good seal. Anyone out there know how the big boys keep the rain water out?

Plan on stitching on a collar, top and bottom to allow for lashing the boot to the mast and your 'bronze sleeve'.
The advantage of the mast boot is that it flexs as the mast and the boat move differently with respect to each other.
Plan on a seam allowance to allow for stitching the canvas into its conic shape.
By the way...it's important to slip the boot onto the mast [b]prior to[/]b stepping the mast. Just a reminder
