A sailing club membership is the best way to get into sailing. I used to teach a basic sailing course for a club that had a fleet of over 20 boats ranging from Rangers 20's and Cal 22's to a Catalina 30. Members paid monthly dues and the size of the boats available depended on which courses they had completed.
I thought this was a great way for folks to experience sailing on many different types of boats without having to put out a lot of money for a boat before they were sure it was for them. Many members ended up purchasing boats of their own, some decided sailing wasn't for them and others simply enjoyed not having to deal with the expense of maintaining a boat of their own.
