Currently under construction: The Dillon Sport C
Sport C is a tunnel boat class using boats about twelve feet long which achieve speeds approaching 60 mph with stock motors up to 35 cubic inches. At these speeds, a tunnel boat can literally fly.
Motors approved for this class are Nissan/Tohatsu, Suzuki, Yamaha and US Marine. The Nissans and Tohatsus, however, dominate the class. Hydraulic trim is allowed in Sport C, and a reinforced cockpit or capsule is required. The minumum weight for boat, motor and driver is 675 lbs.
The Dillon Sport C will be about 12'8" long by 76" wide. The reiforced cockpit is foam-core construction using fiberglass, carbon fiber and Kevlar fabric. The remainder of the boat will be marine plywood, mostly joined stitch-and-glue fashion.
