hard vang means no topping lift?
In someways not being able to use a vang as a preventer is a good thing. A preventer should be a little stretchy (in case you dip a boom or death roll) and should be releasable quickly and reliably from the cockpit and should allow the boom to move fully across the boat under control. When you use a boom vang as a preventer, there usually is too much friction for a quick and controlable release and rarely is there enough line to be able to allow the boom to fully cross the boat.
