Boat was built from kit with many phone calls to Portsmouth, VA by Tom Isaac. Boat was all Okoume and Spruce 280 cu. in. with 265 Chevrolet. The boat had limited success until 1982 when Mercury props, headers, and widened transom with full length air traps made the boat much better. At that time most 280s were Plymouth powered cabover hulls and as the boat started winning heats, there were constant protests. Engine inspections always proved the boat legal but the decision was made to go 2.5 mod in 1984. With a Scat V-4 Chev the boat was very fast but dangerously loose riding. After Tom destroyed his 6 liter the boat was lengthened and run a few times from 1989 until 1991. In 2003, the boat was pulled from storage and refinished.
