OK. You don't speak of
experience or preferences, so aside from
budget, how about looking at a basic
monohull sloop and a basic
catamaran. For the
monohull aim at about 38-40 feet and for the cat a bit smaller (cats have more
interior space per length).
Then see how your preference intersects with your budget. Only consider ready to sail
boats; you don't need to devote your lives to a
project boat. If what you like costs too much, you can go smaller or older to drop the
price.
I'm leaving out consideration of your level of skill sailing. That's a big question.
