Survival? I all depends on the circumstances. One of the possible option in survival conditions is to turtle the boat on purpose, it is far more stable pointy end down. It's also going to slow it drifting giving you more time to think and/or call for help.
Or go head to wind and get the main down. Roll it tight, and attach it solidly. If it it windy you'd be surprised how well you can point or the speed you can reach DDW with just the mast!
