I have a little money on a bet, help me out. I would like to know what product or person,has the fastest 40' plus boat.. I know alot of the race boats, so, the bet is on a boat with a cabin.

V or cat?

I'm not sure, but in a vee it's probably going to be a Hustler, Outerlimits, or a Fountain.

I would guess Skater.

Skater 46 Supreme

If you want a boat that beats everyone else to the hot spots and still pampers you after you arrive, check out the Skater 46 Supreme. This big cat has roomy seating in the cockpit in stylish high-backed racing bolsters, plus a full cabin belowdecks so you can overnight in the highest style. Of course, the Skater 46 Supreme performs true to its champion bloodlines, flying effortlessly over waves and boiling calm water at speeds exceeding 150 mph on twin 1,300-hp engines. A laminate made up of vacuum-bagged S-glass, kevlar, aircraft-grade balsa coring and epoxy resin provides maximum strength at a minimum weight and the hull and deck are fully bonded together around the perimeter.

Hustler 41' Razor with Twin Merc 700NXT = 98mp/h

On a V I would say a 42 Outerlimits with 1075's. Has a full cabin with walk in head. Add a generator and you can overnight on it no problem.

Way too wide of a scope.

V or Cat?
Stock power or custom BIG power?
Piston or Turbine?
What's defines a cabin? "Cover-girl" with two opposing couches and a porta-potti; or Full Cabin with V-berth, opposing couches, microwave, pump out enclosed head, refrigerator, Heat/AC?

Full Cabin, A/C Gen full kitchen, Bath, Queen Birth, Couches, 2 flat screens, 132mph

42 Fountain with 1075's will run in the low 130's

I would guess an Outerlimits or a Fountain. (42')
