I ordered the largest size to add to my existing set for a 42 foot catamaran. I'm not counting on these along, but plan to use them along with my other more expensive fenders. We're going from a side-tie into a slip and I wanted some extras to have for both sides of the boat. In general, I believe these are a little undersized for my boat but that was my choice in purchasing them. Overall, feeling pretty good about this purchase. They seem suitably thick in material and come deflated. The included pump works fine but I was wishing for an electric pump by the time I started the second fender! They are keeping air fine but only time will tell. The included lines are a little short for my use so I'll probably need to replace those later. I made them work on my lowest lifeline. The included bag probably won't get any use as it won't go into my hold with the fenders inside. I haven't tossed it yet but will probably make other use out of it. There was some manufacturing bits on the rubber but that came off with a brush of a hand. Not sure if these will mark up my boat or not so, again, time will tell.
