Building Lazy Jacks

[Mariner4152]

Thanks for the info. Probably build the first pair from a cheaper rope the first time to work out the bugs in the system.

With respect to being adjustable, that was the plan for the check blocks up near the top of the mast then lead the halyards back to the bottom and cleat them off. That way I could raise or lower the lazy jacks as needed. The area of concern for me is where the legs attach to the boom. Do I need the legs to be adjustable or is it Ok to just terminate them at the boom? Should the front legs have more slack to allow for more sail bulk?

Thanks again.
Greg.
