I think I would like a 40' sailboat with a room fwd and one aft and two heads. I suppose I could get along without a second room aft and a second head but I like room to grow. I just realized in my thinking of size that if I hold out my hands that distance (about 3 feet) would be all I would be missing to instead get a 37' boat.
Do you miss 3 feet of length that much on a sailboat? What length boat is enough for you? I hope nobody replies saying a 15' dingy is all they need to live on
