I finally have a great fitting boat cover for my tri-hull boat. I was nervous about the fit but it fits like a glove. Fingers crossed no pooling water anymore...

Good quality and fits perfectly...

This boat cover was unsatisfactory. The fabric was light weight and could not adequately be supported for drainage. The fabric sweated on support beams both wood and plastic. The fit was OK. I returned the boat cover.

I decided to "cheap out" and get the 7 year fabric instead of the 10 year fabric. I honestly don't see myself owning this boat in 10 years. The cover is very well constructed and fits as well to be expected. Since this is a custom cover and not an exact fit for an exact model, it has some areas that it could be tighter in. I think part of this has to do with the fact that my boat is a modified tri-hull and even though this cover was made for a tri-hull, it still doesn't fit quite right. It should definitely get the job done though. I won't know for certain until we get our first big rain and we have been in a drought for a few weeks. The elastic is super strong and the built in motor hood is a nice touch. There are more tie down points than I has straps to secure them with and it trailers okay. Since it has some slack in it, it tends to get jammed back against the windshield while trailering.

The cover fit my 1975 Renken 15.5 open bow. It is plenty wide, overhanging each side by about a foot when pulled tight, but is just long enough to overhang the bow by about 4 inches. The integral engine cover is way too big for my 50 hp Evinrude, but still works fine. The material seems very strong, and has shed rain completely with nothing getting through even thought we have had multiple heavy rains since I've had the cover. The tie down straps that came with the cover work great for me. I use them to tie to my lift when on the lake. The quick-release buckles work good and you can quickly adjust the length as needed.

I recently purchased a boat cover from iboats and am very satisfied with the product. The web site is easy to use and the fit of the cover is much better than the last cover I bought. Thank You!
