OK folks, my current boat ( 16' Sylvan alum) is in need of new transom tie down straps. It currently has the over center buckle quick release type like my prevuous boat had ( 22' Islander) ...I have been looking at ratchet type straps as the over center style seems to come loose frequently. Cant use the retractable type like I wanted as there is nothing to mount them to on the trailer...are the over center type buckle straps faulty, should I try another brand, or is the loosening a common issue? I am looking at ratcheting type to get a tighter hold down with less chance of comming loose, is there a better rachet type (I need dual hooks) that I should look at. My searches havent showed much as to the pros and cons and better vs cheap. So...what is everyones experiences and recomendations. ????
