Ski Kilo (SK) (APBA)

Organization: 

SK Racing Runabout was a flatbottom class in the APBA. It had a 400CI limit, carburetors on gasoline only. Boats had to have seating for 2, be at least 16 feet long and weigh 1500 pounds. Until 1967 they had to have fixed cavitation plates.

It was eventually combined with Pro Comp (PC) to form the Pro Stock (PS) class in 1988.
