By Mike Smith Pacific Asian Enterprises offers bulbous bows on its Nordhavn models ranging from 62 to 86 feet LOA, but not on the smaller boats in the line. The Neville 47 is built with a steel hull for strength. Charles Neville prefers a conventional bow; a single, nonelectronic diesel powerplant; and metal construction. Patrick Bray chooses to protect his twin props with hydrodynamically efficient skegs and rudder-end plates. His bulbs are larger and longer than you typically find on motoryachts. While at rest, the bulb is barely visible, but underway it creates its own bow wave to partially cancel the hull's wave and reduce resistance. The 462 Diesel Duck is for hardcore bluewater enthusiasts, with a sailing rig for get-home power.
