I am very disappointed with these fenders. I have 6 that I use on a 46' houseboat and I have had to now replace 4 of them so far. They have all torn (ripped) at the ring where you tie the rope. I keep buying the same fenders because I want them to match what I already have and it is easier (less expensive ) to purchase 1 or 2 at a time instead of replacing all 6 at once. I would not receommend these to anyone.
