I was involved with power boats and canoes at a young age but no sails.
While in the military I got a 4 day pass with my crew and they dragged me onto a 22 ft catalina. I didn't think much of it but since they brought the beer and 2 of them didn't drink, (even had designated drivers back then) I went along. Once we killed the outboard, I was impressed. One of the crew was a licenced captain and he saw my interest and just started teaching me how to do it... Over the rest of my tour we tried to get in some sailing when ever we got a couple of days off. That lead to my buying a 30 ft S2 after selling my house in a divorce and have been living on it since. So I'm not sure if that is formal training or just going for it with friends...
