for the distance races we put on the loop/ball system that jake mentioned. It really straps you in well to the boat, so well in fact that if both crew are chickened in the rear, it will save a pitchpole from even happening.

Plus, if you're a crew and you're washed out by a wave, it can keep you from knocking the skipper off the back of the boat.

The loop/ball system is very easy to get in and out of and can be disengaged while under pressure. In fact, if you're not in the trap ring, then the ball isn't going to retain you during a capsize.
