Some call it safety position. On some cat-rigged boats, you can let the sheet out most of the way, heel the boat to leeward, and put the tiller to leeward.
* Capsize. Not as crazy as it sounds.
I love that! I wouldn't have thought of that. Use your boat as a sea anchor. OTOH, if there is lightning in the area, you may not want to be in the water.
