[quote=MN3][quote] Both ends have to attach to something solid in order to apply proper tension right?[/quote]
both ends live in cleats. when both are cleated and taught / downhaul is applied
when either end is released from the cleat there is zero downhaul applied

but i suggest you search for catamaran setups and you should see a 6:1[/quote]
