A Cape Cod Knockabout is an 18-foot centerboard one-design sailboat. They are sailed primarily out of upper Cape Cod harbors in Massachusetts. The Cape Cod Knockabout was designed by Charles S. Gurney and first built in 1925. It has withstood the test of time, transitioning from a wooden hull to a fiberglass hull. Active racing fleets can be found in Megansett (North Falmouth), Waquoit (East Falmouth), Lewis Bay (Yarmouth), and Woods Hole (Falmouth). There is also a small racing fleet at the Split Rock Yacht Club in Essex, New York, on Lake Champlain. Many knockabouts throughout Southern New England are still used for pleasure sailing, as well. The Town of Yarmouth Recreation Dept. owns and runs a large portion of the Lewis Bay fleet, where most of their boats are used for sail training. Hundreds of sailors of all ages have gone through the Yarmouth program using the knockabout to learn on. Yarmouth also maintains a select group of their knockabouts for their racing program. Various summer racing series are organized by individual fleets. The Cape Cod Knockabout Association holds an annual regatta each summer at one of the above four Cape Cod locations on a rotating basis. Local fleets are generally increasing their numbers. Cape Cod Ship Building in Wareham, MA manufactures the boat.
