Main, boom and jib sheet blocks of different de-sign or make may be used provided the pu
r-chase advantage remains equal to or less than
7:1 on the mainsheet system and 3:1 on the jib
sheet system unless specified otherwise in ind

The downhaul can't be more than 6:1... the cleat must be on the lower block and fixed so it can't be adjusted from the wire.
