We all know that a deep-bodied genoa totally blocks off all vision on the lee bow, especially when you’re close-hauled and well heeled over. The person on the helm has a sector of anything up to 60 degrees where he or she is totally blind. Boats can creep up into this zone with amazing rapidity, especially the ones you just missed seeing last time you peeped around the leech, so detail someone off to look out, and keep them at it. It’s a great job for a youngster who’s been looking bored and needs responsibility!
