Looks like what they call a cathedral hull. A V with deep chines, forming 2 semi-tunnels. Smaller Boston Whalers have this type of hull design.
Fast and stable, but they have a tendency to pound in rough water (as anyone with a BW Montauk.
A Whaler friend of mine came out on my boat, and returning through 4 or 5 foot seas, I asked how my boat rode compared to his Whaler. He replied that there really wasn't a comparison, as he wouldn't be out in that stuff.
