Where do we even begin???

We have extremely limited knowledge on boats. All we really know is that we need one that is big enough to hold our supplies, preferably still having enough room to be comfortable to live aboard for a few years, and that it needs to be small enough that 2 people can manage it without concern. Based on what I have come across so far, I am thinking we need something about 30′, but that could easily change if we see a boat and fall in love with it. Also, some sources say that 40-45′ is recommended for bluewater sailing. We aren’t going for speed, so smaller isn’t really necessary. I read about the Caliber 40 LRC, Hylas 46, Island Packet 420, Tartan 3700, and Valiant 42 as being good, affordable bluewater sailboats. The Tartan and Valiant have been fairly prominent in my readings so far, as well as the Westsails.  We also aren’t sure if we want catamaran, sailboat, or something else entirely, although we also aren’t really quite familiar with what these mean and what our options are! I think we need to start going to weekend boat shows! We are planning to take a basic keelboat sailing class soon, so hopefully we will know more about what we are getting into!!!
