We are on North Carolina and have a lot of humidity. This has held up well so far through several storms and 100 degree temps. No mold, no water in the boat at all.

Though it claims to cover 18.5 ft boat, the cover has is just long enough (2 inches). For my SeaRay, there is excess material on the sides. As a result, it sags and pools water (despite the centerpole). The material repels water as promised.

Fit perfectly even with a swim ladder! Customer service was excellent too. Would recommend buying the rods to hold it up as it will collect water if you dont. Very happy with the purchase.

I think the boat cover I bought recently is great! However....The tie down strap clips need to be a bit more stought. While tightening the cover so water would not puddle on it a few of the clips broke. The cover looks and performs great!
