Operational history

The design is regulated and racing organized by a class club, the ''National C Scow Sailing Association''. In a 1994 review, Richard Sherwood wrote, "As may be seen from the rating, this cat-rigged scow is fast. Scows were developed in the Midwest, but the C-Scow can also be found in Texas and California. There is extensive control ... These boats are one-design, with strict control of hull shape."
