Sail a yacht. I did it, and by 'it' I mean that I manned the helm for a while. Occasionally I did some winching, or tailed when someone else winched. Fed out some slack as someone else winched, sometimes too.
Me - sailing (or rather, motoring) out from the Lakki Marina, on Nisos Leros.
Sometimes it was hard work, but mostly, when you're sailing around the Mediterranean/Aegean Sea, it's really just lying around the boat in the sun. Or, if you're like me, concentrating very hard on not being horrifically ill, because it turns out you get seasick.
I'm counting this (number 87) done. Woo!
