My current thinking is some kind of camcleat scheme such as suggested by Dave. I'm trying to not have too much hardware or lines crossing an already constricted walkway around the wheel. I also want the ability to release the wheel in a hurry which makes Tom's low attachment point not so good unless I add a block or two and a vertical line or two. Since Tom's setup used a Sailomat, he didn't really need to lock down the wheel except perhaps at anchor when quick release would be less of an issue.

I'll see if the Jefa/Whitlock distribution folks have any suggestions.

We fired up the watermaker for the first time today and liked watching it and the reefer totally powered by solar. Things are coming together. Departure scheduled for one month from today.
