[Rhodes22-list] How to: A Trouble-free Furling Main | Sail Magazine

[Mike Riter]

That's a really good looking sail Jay. Looking at the photo, I'm curious
about a couple things. First, did you have a Doyle before having the
Evolution made for your boat? And can you tell a noticable difference with
the extra batten?
