The owner requested a 20-knot cruising speed, so weight savings were vital. The 104’s hull, deck, superstructure, bulkheads and cabin soles are vinylester-resin infused, multi-axial E-glass reinforced, foam-cored fiberglass. Cabinetry and partitions are honeycomb-cored. Powering this 211,500-pound yacht is a pair of 1,900 hp Caterpillar C32 ACERT diesels. At 75 percent engine load, the 104 sped along at 21.1 knots, with the Cats burning a total of 155 gph. She topped out at 25.5 knots with the diesels burning 201 gph, resulting in a range of about 504 nautical miles. With 5,200 gallons of fuel, just pick your waypoint and go.
