I learned sailing at CGSC when I was about 10, but I recommend an ASA school
for adults. Learn the theory and science instead of the racing rules. When I took my first ASA course, I learned there is a lot more to know than how to make a boat go fast.
But try to learn on a small boat, not a 30+ footer. You will never be as good a sailor if you start on big boats, because you don't get the "feel" as well as on a small boat.
Would you start teaching a kid to drive in an 18-wheeler, or a small car?
Whatever you do, you have a great place to sail. I grew up in Coral
Gables/Coconut Grove, but I left in '73 to work in Chicago. Finally returned to FL in '95, to Jax. Good luck.
