Obviously, a catamaran makes the best liveaboard, assuming you have a place to put it.
While I love PDQs, I think the new 42 would be over $300K, and very few on the used
market. However, I've been very impressed with the Manta 42:

What's a few best liveaboard sailing vessels, under 55 feet and under 300K on
the used market?
