A 20-knot north wind generated three- to five-foot seas nearshore that quickly built to eight to 10 feet just a short way out in the Gulf Stream. Drifting beam-to those big seas proved more comfortable than I expected, thanks to a very short roll movement and gentle transitions. During speed trials in the calmer waters along the beach, I managed a top speed of 41.3 knots. Powered by a pair of CAT C32 ACERT diesels rated at 1,900 hp, the V-12 four-strokes carry a 1,959 cubic inch displacement. Thanks to computer mapping and other technological advances, these engines generate 15 percent more power than previous non-ACERT C32 models.
