|The Nordhavn 57 is a full-displacement passagemaker with all the necessary features of an ocean crosser. The construction is to the same heavy scantlings as her sister ships, but the design differs in styling and interior volume. The 57 maintains a rugged, commercial look while interfacing a contemporary elegance, and offers a level of performance that expands the envelope of top cruising speed and long range potential. The hull and its bulbous bow have been fine-tuned at the Engineering Facility at the University of British Columbia. Maintenance Strakes have been developed which maintain a moderate draft, and freeboard and superstructure height. The maintenance strakes not only provide added engine room height but enhance the vessel's performance by up to 2 percent depending on the speed selected. Working in conjunction with the bulbous bow, the strakes have a positive effect on the wave-making characteristics and reduce resistance. A combination of a parabolic-shaped bulb, fuller sections aft, and a stern designed to minimize drag-inducing suction at high cruising speeds, allows this vessel to run efficiently at speed - length ratios of 1.6, or approximately 11.5 knots. There is a minimal efficiency penalty at lower 'ocean crossing' speeds, but this does not affect capability due to the vessel's substantial fuel capacity. The 57 offers cruising speeds above what is normally possible in a full-displacement hull while maintaining the benefits of this hull form, such as ocean crossing capability, reduced noise and vibration levels, heavy construction scantlings, and greater safety - comfort. For semi-planing hulls to achieve planing speeds, weight must be minimized which adversely effects seaworthiness and long-range capability. Additionally, the seakeeping qualities of the higher-speed models are compromised due to their light displacement - length ratios, small rudders, and shallow keels. The 57 features an interior volume - overall length ratio higher than previous Nordhavn designs. This increase in space is due to a greater beam - length ratio, increased volume in hull sections, and the beam carried farther aft. Additional innovations include a walk-in engine room with dual work benches, a deep lazarette with shelves, a large cockpit, a swim platform with access door, a large flybridge, and fiberglass fuel and water tanks.
