There's "learning to sail" and "learning boating".
A lot of new people show up wanting to sail, who have NO boat experience whatsoever. Those people are at the greatest disadvantage when starting out. Not only are they trying to get the boat moving, and steering, but they are trying to understand channel markers, and who has the right of way, and what the depth of the water is.
I grew up in South Florida, on small boats my whole childhood. Joined the US Navy and did some navigation and radar there. When I decided to learn to sail, all I had to worry about was making the boat move. My brain wasn't busy trying to understand everything else about water-borne navigation, so I was free to focus.
I bought a book, a Coronado 25, asked some questions on the web and went sailing. Learning to sail well
...now that's a whole other story.
