My worst sailing experience was getting stuck on top of three perfectly spaced rocks. Had high swell waves, I was looking at the coast. Wave lifted my longboat up, and dropped it right in the middle of the rocks, two on one side, front and back, one on the other side in the middle. That's when the waves decided to calm down. Tried to break the rocks with the pick but could not hit them from the boat and they were just steep enough that i could not stand. Finally had a large wave come along and lift me off.
