That leads to the final vital aspect of stability mode: constant vigilance. If it's windy enough that you're sitting directly on the leeward rail, you should be facing backwards and calling out puffs. Your skipper will be focused on playing the sail and keeping the boat upright, so it's important for you to let them know what's coming your way. If you see a death puff headed towards you, stay calm; inform your skipper when it's going to hit and whether it's going to be a knock or a lift, crank the vang, put down the board, and spread your weight. Once you've weathered it, ease vang, raise the board, and centralize your weight at least a little to keep your boat competitive and flying downwind. There is one catch—you as the crew can do all of these things right, but if you're sailing by the lee and a big lift hits your sails, you'll still death roll despite your best efforts. So don't let you skipper sail by the lee in these conditions! The cassette tape telltales that you should have put on the shrouds are not just for their eyes; if they're streaming to windward instead of to leeward, point this out to your skipper. They should then make the decision to head up or execute a careful jibe, returning your boat to a relatively safe angle to the breeze.
