Exactly...BTW, on a smaller boat, you might not need a six-to-one purchase, and might be able to get away with just a four-to-one or so.

Thanks.

Yeah, I am pretty sure it's 4:1 on this boat.

I'm not sure but I think this arrangement is called a Crosby rig. 4:1 is more than adequate for my 23 footer. The single cam cleat is mounted on a Harken 144 swivel on the port side, along with a hexaratchet block. I've never felt the need to switch the ratchet on. The sheet is easily cleated or released with a flick of the wrist from either side.

I use a powerful boom vang in lieu of a traveler. I started with a 3:1 tackle and added a single block to cascade it to 6:1. The picture shows another block in the system to make it 12:1 but that was TOO powerful--I bent the boom.

I like your boat. Beautiful.
