Sport C is a national powerboat racing class in the Outboard Performance Craft (OPC) category of the American Powerboat Association (APBA).
It is very similar to 550cc Supersports Class which is raced in Australia, and the S550 or Formula ADAC class raced in Europe.
Several hull types and motors are approved for Sport C, but the typical rig is a 12-foot long tunnel boat powered by a 40hp Nissan or Tohatsu. Top competitors in Sport C race at speeds of 58-59 mph.
Boats raced in Sport C are required to have a reinforced cockpit or a capsule.
Most Sport C racing takes place in Minnesota and California, but there a few more racers from other parts of the country, including Missouri and Florida. Sport C racers meet annually at the OPC Nationals in Kankakee, IL, to participate in the championship races held there.
After several years of trying to break into Sport C, 2011 is the year I finally got it done. For 2012 I've got an entirely new boat, the Dillon Sport C, seen below in Detroit Lakes, MN. You can follow with the 2012 build HERE. My Sport C trials and tribulations are chronicled HERE.
Plans are available for the Dillon Sport C.
The Dillon Pro Tunnel, though a little smaller than the average Sport C boat, could conceivably be used for this class. A proper cockpit (not part of the plans) would have to be built/installed.

Local powerboat racing is a family-oriented motorsport where friends get together to share a passion. Racers are always ready to share advice, tools, equipment or muscle, and help their fellow racers get the most out of their rigs. We save the competition for the races themselves.
