I never set foot on a boat before then. A friend bought a racing sailboat (Mirage 35, I beleive) and I went out sailing one day. And that was it for me. It was over 10 years ago. I bought my first sailboat - Beneteau 235, shortly thereafter, but steadily moved to cruising boats since (turns out I like working on them).
I did take ASA courses and probably still have my book with little stamps somewhere out there.
