The best way to choose is just get a copy of various magazines from a news stand and see. There is a lot of variation in what people like.
For example, many people like Latitudes and Attitudes, but I won't even pick one up out of the book exchange any more. (Many marinas
have a shelf where sailors drop off books
that they have read and pick up books
that others have left.)
I like Cruising World (www.cruisingworld.com
). They run articles about boat handling and maintenance
. They review boats. There are a fair number of "I went there and saw that" articles, which can be interesting for how people do it, even if there is no way you plan to go to that part of the world.
If you're not very familiar with sailing, something like Cruising World or Ocean Navigator will give you some good insight. They aren't really aimed at somebody with no sailing experience, but they have a broad enough coverage that a beginner can get a lot out of it.
But then I'm interested in cruising. If you are in to racing
, you might have a different view.
