I'd be very careful using fender cleats to spring unless I was sure they were well secured and backed behind with a substantial backing plate.Originally posted by Chinewalker:<br /> I have fender cleats down the side of my boats, spaced every four feet or so. Bumper lines have a loop that keeps it an average height - set for my personal docks - and I can wrap it around the cleat to bring it up if needed. The extra cleats also help when springing the boat for parking in not-so-protected waters....<br />They get unlooped and stored in the boat while we're underway. I absolutely LOVE it when other folks don't pull their fenders in while underway. I haven't had to buy one for my own boat in years!<br />- Scott
