I have this cover for my boat (26D version).
This is the best investment one can make for any of these boats.
After the summer sun here on the desert. The cover has held up great for the year I've had it. It looks brand new and hasn't faded. The boat itself looks better than ever, particularly the decks and I will no longer have to clean and treat them all the time to keep them looking good.
Access to the cockpit and boat interior is good, without removing the cover. I think a zipper at the back would be better than the grommets and lace-up method, but it does work.
Rain water/ snow will gather on each side of the mast, between the stanchions. This really puts some stress on that part of the cover AND the mast itself. Agree the tennis balls on stanchion ends are a must and also a center support for the mast, at the mast step. I've thought about installing a couple tarp drains in the cover, with hoses leading to the cockpit floor/drain. This would solve the rain water issue, but not the snow build up issue. It doesn't rain or snow that often here on the desert, so for now, I've just been going out and sweeping the water/snow out of the low spots, when it does
Anyway
LOVE this cover. It's pricey, but worth every penny
Best Breezes,
