I think asking for info here is a good start. As was suggested by another poster, get down to the water
and offer yourself as crew. The more you do that the more you learn - at least that's how I learn, anyway. It also gives you perspective on different boats/rigs and how they sail, as well as different sailers and how they sail. If there is a yacht club or other entity that offers lessons, take them. If there are races nearby, try to get on crews. Once you get a feel for a boat, buy a small one and take her out a lot. The reality of sailing is - if you can sail the small ones, you can sail the big ones. All the rest is learning
how to tie the knots!
