I haven't actually seen any of those backrests in use. Sailors who race their Waves don't use them because the backrests would be in the way for hiking out.

But when I am out cruising around just for R and R on my Wave, I often think about designing a little, adjustable recliner chair to mount on each side. Problem is, I would probably fall asleep.

As far as the Hooter, Rick put one on my Wave. I was surprised to find that I really enjoy it for pleasure sailing -- makes it like a whole different boat. But I am going to try a couple of different sheeting plans (still in my head) for the Hooter, because I don't like the one I have.

P.S. I forgot you asked about the zipper sail for reefing. I didn't even know they had such a thing, but I really can't imagine having to reef a Wave.
