For what it's worth, I gave up on the clam cleats, except on the jib halyard. My main halyard and all sheets now run through Harken cam cleats. (The sheets lead to tracks I installed atop the coaming, to accommodate the genoa. The cars carry cam cleats. I usually use these same tracks even for the working jib, which I in fact rarely use.) I first made the switch on the main halyard. Especially when single-handing, when I get the main up, especially in a good wind, I want the halyard to set immediately and without any question as to whether it's going to slip. And I got tired of seeing slack in my main and realizing that the halyard had slipped through the clam cleat. The clam cleats seemed to wear quite quickly, too. It's just easier to release halyard or sheet from a cam, and trimming is, well, a breeze. Steven Paint4Real@aol.com ************** Looking for a car that's sporty, fun and fits in your budget?
