I bought both Model A and Model B. I have two Hobies kayaks, one is 10.5ft long and 34in wide. The other is a 13.5ft long and 35in wide. The Model B fits perfectly although it's longer than I need it. The Model A could only reach halfway to the 34in mark. I really really like this material and I've already thrown the box away so I did what I had to do, cut the zipper down the middle...yes I know, that was drastic but I don't want to deal with returns. Note that they do not specify width so regardless the length, if your kayak is under 34in, get the Model B.

I have a 16.5 foot Wilderness systems Tsunami , it was way wider than need be but can wrap it over itself and then strap it. Down side is it will fit only 16 feet, so I have to remove the rear rudder when bagging it up. Pro is it is of very good quality and easily slides over the kayak.

Kayak life expectancy is reduced by UV light and temperature. The cover allows me to store it outside and minimizing these concerns. Get yours now!
