The Nordhavn 64 draws on many of the elements of other Nordhavn designs, but it is also uniquely beautiful and elegant in its own special way. The generous interior volume is made possible by the relatively high bow and extra freeboard of the overall design. After extensive tank testing and actual sea trials of its various models, P.A.E. determined that there is no downside to adding more freeboard to its designs as long as weight is kept low. "Of course aesthetics are an issue with extra freeboard, but when we get into the 60-foot range, there is enough length to give the boat a very attractive profile," Leishman said. Beyond the obvious advantage of providing more volume below, there are sea-keeping advantages to the high bow and deck level. The bow provides extra buoyancy when punching into large head seas, and the deck takes on less green water in high seas. Because the added height provides more volume below the cabin sole, the engine, fuel tanks and water tanks are positioned very low, ensuring superior stability. P.A.E. is able to use its bulletproof 'gravity feed' fuel system, which has proven to be extremely reliable and easy to use. Corrosion-free fiberglass fuel tanks feature human-sized inspection plates, adding to the trouble free, long-term service of the vessel.
