Cam cleat should work fine especially if the sheet already has taken a few turns around a winch
. Have seen a few boats set up that way and didn't hear any complaints. Mainsheets on most boats are secured with cam cleats
. At the end of a four part tackle probably wouldn't put the force on a main sheet that genoa
sheet could have on it, however. Would not use a cam cleat that has a fairlead before it. With a sheet, you need to be able to pop it free and pull the sheet upward off the winch
. Also a fair lead will be subject to hangs ups of the rope
passing through it. You want a Jib
sheet to run as free as possible without having to deal with hockles in the line getting jammed anywhere.
Personally have always been able to pop the sheet out of a cam cleat and have had some with a lot tension on them, enough to distort the cleat. CLam cleats
are another story, however.
