Hey well i haven't read what the others have said only because i really dont have time, sorry boys. Well to be honest a good sailor doesn't go over very offen because they dont think about going over. Well In terms off where to land, i think anywhere close to the boat is good because its a race so you need the boat up ASAP. I know when i sail my boat i normally have a contoled capsize and well i can do a dry capsize but when the winds are wild im really landing in the sail. Dont worry about hitting the sail its probs the strongest part of your boat anyways(only if you have a new boat).
Nose dive. In a nose dive well all i have to say is try and stay away from the boat.
caping sideways. If you have to go make sure your close to the boat and get it up asap. Dont try and land in a possition where your going to have to take your time like doing a dry capsize. When i do one i normally jump off anyways just to speed things up.
If your thinking of boats to get i would seriously think about can you contol something faster and if you can do you really need to!!
Well sail fast and have fun.
