My friend was planning to sail transatlantic alone on a tiny sailboat. I know he is capable of this mad shit, both in skill and in level of recklessness, but I don’t know he did it (he has adhd so hard that listening to his accounts of things happened is a rare and chaotic experience). But from what he said, mortality rate in these single person adventures is non negligible. He was in some sort of chaotic depression mood at that point.

I understand many people in Scandinavia sail to Americas occasionally. There is famous Greta, I think, who did it with a tiny crew? With crew and radios and reasonably sized boats, it must be much safer these days. I don’t like traveling myself, so it’s mostly second hand knowledge.
