I'm looking at the covers Iboat offers. They are boat specific, but for my boat, 1984 23' Webbcraft Cuddy, they only offer a Semi-Custom cover. The price is very attractive @ $275, but are they any good? I assume there are no reinforcements over the windshield and other stress points, nor is there a rope through the hem, but there is a shock cord. Not sure how I would secure it when the boat is in the slip as it is all summer. Would I just be better off with a locally made custom cockpit cover?? Anyone using these semi-custom covers?
