The Nordhavn 76, like it’s smaller sister, the N72, carries through the progression of P.A.E.'s modified full displacement (MFD™) hull design which achieves superior sea-keeping qualities, longer range and greater speed than other full-displacement vessels of similar sizes. Evident in the other models in the line, the MFD™ hull design features full stern sections to minimize pitching motion and to maximize weight-carrying capacity. The unique shape of the stern section also helps maximize the top cruising speed capable by reducing drag caused by "squatting", common to full displacement hulls running at high speed-to-length ratios. The MFD™ hull design includes a slight tunnel area for the propeller, allowing a large diameter prop to be used without increasing draft. This large diameter prop increases efficiency and reduces cavitation, creating a quieter running boat.
Employing innovative tooling design, P.A.E. also offers optional engine and bow configurations. While the standard configuration is a single-screw vessel, the Nordhavn 76 molds have been designed to include inserts for twin skegs as part of the original hull lay up. Bulbous and conventional bow molds are removable and interchangeable allowing the buyer to choose either bow and still receive a one-piece seamless hull.
P.A.E. did not rely solely on theory as it developed its MFD™ hull for the Nordhavn 76. Instead it invested heavily in a complete tank-testing program at B.C. Research in Vancouver, Canada. Among the breakthroughs achieved during this extensive R&D program were the addition of MAINTENANCE STRAKES™ to the bottom of the MFD™ hull, which create gentle bulges in the hull form directly below the engine location. Not only do these revolutionary devices provide six feet four inches of headroom in the engine room, they also allow the engine to sit lower for enhanced stability, minimum shaft angle and optimum thrust. The tank testing also revealed a surprising 2% increase in overall hull efficiency due to the positive effect the MAINTENANCE STRAKES™ have on the vessels' performance at higher cruising speeds. An interesting first with the Nordhavn 76 is the incorporation of root cord fairing pads into the hull design. The tear drop shaped flat surfaces port and starboard on the hull conform to the sweep of the stabilizer fins and insure a close precision fit between the top of the fin and the hull surface throughout the full range of the fin movement. This tight gap prevents “spillage” of water over the top of the fin and thus increases the efficiency and performance of the fin foil dynamics. Similar gains are found at the bottom of the stabilizer fin by use of the ABT TRAC “winglets” which also reduce spillage and increase efficiency.
The performance chart indicates a practical, economical speed range of between 9.5 and 10.5 knots for the Nordhavn 76. At these speeds, she has a range of between 3,800 and 2,400 nautical miles, burning between 9.7 and 17.4 gallons-per-hour. It is quite revealing that most long-range or rough weather cruising is done at speeds below l0 knots, even by boats capable of far higher speeds. Not only are many boats uncomfortable at higher speeds, but also their owners soon discover that all the noise and rapidly moving scenery are not conducive to an enjoyable voyage. Additionally, if an owner has long-range cruising plans, the economics of running high horsepower, planing boats often preclude the desire to go faster than displacement speeds. Compare burning 8 gallons per hour traveling at 8.5 knots in a NORDHAVN 76 with 30 gallons per hour in a planing boat during a four-week cruise while running 4 to 5 hours per day, and one quickly appreciates the efficiency of a full displacement hull. Even if the faster boat's number of hours per day are reduced to compensate for higher speeds, there is a huge difference in fuel consumption and operating costs.
Most importantly, the crew of a Nordhavn MFD™ design will arrive rested and relaxed, ready to enjoy their new surroundings. After completing his first long voyage, one Nordhavn owner, who sold his fast, planing boat said it best: "This was the fastest voyage I ever made on the slowest boat I've ever owned."
