I am partial to Ulstein hulls. Commercial stuff, in terms of ships.
I do like the ship-yachts, though. Those are true world cruisers, as opposed to a SF. Sure, you can take a 70 foot SF just about anywhere, but you have to have the fuel stops and plan around the wx. Something like the one above, you load fuel and go. Seaworthy.
