I made a set of stowable lazy jacks for my boat and the two charter boats I crewed on both had them. I have not the issue with lazy jacks that people have mentioned here. My boat has partial battens, one of the charter boats was a gaff rig, and one was marconi with full battens. I am just not sure why people have so many problems with them. In my opinion they are the biggest bang for your buck. I find them almost essential for single-handing.
