These days, supersize speedboat technology has been pretty well sorted out. Back then, such a design was pushing the envelope. I infused my effort with high-speed, patrol-boat DNA with the help of a D.C. Beltway subcontractor. Her scantlings called for a tough, longitudinally framed aluminum hull and a lightweight, cored composite deck and superstructure. A pair of 16-cylinder diesels pumping hundreds of gallons per hour would have yielded 50 knots, and surface-piercing props would have provided the maximum visual effect.
