One place to start, if you have no
experience at all, is to take a class. You don't mention where you are located but most countries there is some sort of organization that teaches
boating and sailing.
You might spend a few hours reading through previous discussions on this forum. There are usually several people every week like yourself that have no
experience and want to learn about
boats. Do a little search in the
archives and you will find lots of reading.
