When pressurized the boom vang will contract and pull the boom downwards. The boom vang needs to be easy to manually handle.

The opposite happens, the mainsail depowers completely, the little green arrow disappears, and the spinnaker happily drags the boat to windward, jibes the boat and someone, usually the bowman, ends up with wet feet.Set your vang tension using the top batten angle to the boom as a guide, and do not blow the vang to solve a death roll downwind. To summarize: use high quality lines and block, make sure your floating block goes all the way to the boom vang key when it is off all the way, set your max off knot at the right tension, use a plastic handle, and mark your vang line for 90º, block to block, depower 1 and depower 2.
