Interior plans call for an open, charter-style salon, forward cabin, over/under single bunks in the companionway and a single head. As befits a working charter-fishing boat, you'll find tackle storage, dry lockers and a bait freezer below. But even workboats demand some comfort, so BB includes a 24,000 Btu Cruisair air conditioner powered by an 8 kW Phasor generator. Though standard power for charter purposes would be the twin 575 hp Cat diesels offering about a 27-knot cruise, you can order this 57 with up to 1,015 hp Caterpillar C18s. But with the smaller C9 Cats, you can expect to burn a measly 35 gph at cruise.
