Lots of folks are going to tell you to get a bigger boat, but you don't have to listen to them!
Many have been happy living and cruising on 25-30 footers. The smaller the boat, the less it costs you, the less time you spend fixing things, and the more time you spend sailing! Also, as you're just starting out this doesn't have to be your "forever boat", just your first boat. You can always do what so many do and get one 5 feet longer years later.
