Comfort is delivered via ride quality too. Test day’s blustery weather kept our helicopter grounded “on call” and us on station in a steadily building chop. In those gray whitecaps, the Cruisers Yachts 390 EC fared well. Landings were soft — pounding more an expectation than an occurrence. The 390 EC felt buoyant. Running down-sea, it tracked admirably straight. Weight savings in the form of balsa-core construction, resin infusion, and careful materials and accessories selection help it to achieve excellent speed and performance. For example, we hit 40.3 mph powered by twin 430 hp MerCruiser 8.1 HO Bravo Three X Axius Premier sterndrives. But as the seas built to those described, we were most comfortable at about 22 mph.
