Rick here first time post.
I have built a 15' mast and 15' gaffs and booms using 1" hollow fiberglass tubing. I would layer wraps of cloth around in 45 deg. going up and down and the, run 2' strips lengths wise all the time sanding it to the taper from 2" to 1 1/2 at the head I put a 1" dowel in the top 2' inside and 3' out and tapered it to 1 1/4". In the foot of the mast I put a piece of 1 1/2 " alum. over the first 2' for the boom to ride on. Inside the bottom of the alum. Tube, I put a hard wood dowel inside and epoxied it in and left 16" out to slide in the mast housing, which is heavy wall alum. 2' long.
I did a static test by putting it in a metal fence post sail was 14’X 12’ lanteen. On that day the wind was a force 4-6 I was holding the sheet and a gust hit so hard that it pulled me off my feet, but it did not break it just flexed and spilled the air out.
I have had nothing but good luck with these. It is heavy on the bottom end but I still anchor it to the deck. If you have any ?'s email me.
Thanks for this site Rick
