A catboat is a boat traditionally fitted with a gaff-rigged sail on a single mast set well up in the "eyes" of the boat. Cruising catboats have cabins and normally range in overall length from 16 - 26 feet. Others are fully or partially decked and suitable for day sailing or camp cruising.
The Catboat Association burgee™ is a white gaff-rigged sail on a field of blue. It was designed by the late Lois Darling (illustrator of Kenneth Grahame's The Wind in the Willows), and a long-time member of the CBA.
