The twin Cummins QSB 6.7 550 hp diesels are a perfect match for this 38-foot hull. We ran the boat from Farley State Marina in Atlantic City, New Jersey, using the joystick to pick our way through the slips and bulkheads before switching to the single-lever controls for the run to the inlet. A 20-plus-knot wind from the east had blown through the night, generating solid 2- to 4-footers. The Billfish handled it beautifully at slower speeds, but even better when the throttles were pushed up to 30 knots. The new bottom really shines in tight turns, and when the boat was turned hard over in a near-full throttle 360-degree turn, it accomplished the task in about three boat lengths without cavitation. The boat also does an admirable job in reverse, making short work of quick direction changes.
