some 20 plus years ago when a boat to windward lost it dinghy off the back. I retrieved it as it blew past and took it back to the only boat to windward so I knew where it had come from. It turned out to be David's. He handed me a new tape as a way of thanking me. As I recall, he was a pretty nice guy. I didn't have a clue who he was until I put two and two together. It was pretty funny.
