The main sail on the Liberty Clipper was something like 800 square feet. We didn't have cam
cleats or
winches. On all the boats I worked on, you were never allowed to put a hitch in any halyard, sheet, or falls. It was considered poor seamanship. I will say that I still don't use hitches on my own boat very often. If you need to have two
lines on a small
cleat, I geuss you'd have to hitch them off. We used the slippery hitch for the falls on one boat I sailed on, but I can't remember why.
