You have gotten some very good advice here. I would add that if you can buy the Seafarer at a very reasonable price and owning it does not cut into the family budget for going out to diner and other entertainment then it''s as good a boat as any to start with. Just don''t plan on this being the boat that you will purchase, load, and sail away with, as it sounds like you have much preparation ahead of you first.
However, there are all types of people and none of us know your lifestyle. I''ve seen folks who with a back pack and a pair of sneakers can head off to just about anywhere, but most folks seem to require some comfort level.
You know who you are and what your minimum requirements are. I think back to a couple we knew who lived aboard year-round in New England with their dog on a Columbia 26. Not for me but everyone has their preferences.
Good luck to you and don''t give up the dream. It''s definately achievable. John Gov.
