Keith,

<br>Forget moving the jib cam cleats, just replace the jib blocks with Ochsen self holding blocks. I think they're still available at Murray's. That's what most of us did when we were racing 18's back in the late 80's. I still have them on my 18, and used to have them on my 20. (When I had a 20, which I don't anymore.) With the Ochsen blocks, (sometimes called Oxen blocks) it doesn't matter where you are on the boat, just pull the sheet in an inch or two and it releases. Pull it in again and they hold. They work kind of like a window shade. My wife won't sail on a boat that doesn't have them, at least not willingly. They will slip a little in very light air, but you just get the crew to hand hold the sheet in those conditions. The rest of the time, they work great. Hope this helps.<br><br>
