In my continuous effort to make things harder and more complicated, I've dreamed up a new mast hoop an it's attachment.
I'm not a mast hoop fan, but some like them and having the need to make some currently, I thought there has to be a better way. In the image you'll see a hoop, but open at the back, where the sail would normally tie on. I picture this being PVC, heat bent to shape, but on 3" or larger masts, I'll bet I could bend some oak (laminate thin slices) into this shape too. This one is 4" around, 1/8" thick and 1" tall, with a 1/2" hole.
The sail slides into the gap at each crinkle (what most call a grommet), aligning the hole in the grommet and the hoop. Next comes the home made insert, which is simply a hunk of HDPE turned and sawn to the shape shown. The idea is to have a plug like thing go through the hoop, grommet and the other side and click into place. You'd just pinch the one end and push the insert back through to release the hoop. This means not having to pull the mast to get the hoops off and the sail can be removed and put back on, without the need to tie each hoop.
At first I was thinking a barrel bolt and button head receiver sort of deal, but trying to decrease the pieces, I came up with this instead. So, what's 'ya think?
