A Cape Cod Knockabout is a one-design class of 18-foot sailboat sailed primarily out of Upper Cape harbors in Massachusetts. Knockabouts were designed by Charles S. Gurney and were popular in the 1940s and well into the 1970’s with fleets of 50-60 boats at the annual regatta of the Knockabout Class. There are still active racing fleets in Megansett (North Falmouth), Waquoit (East Falmouth), Lewis Bay (Yarmouth), and Woods Hole (Falmouth). Many knockabouts throughout Southern New England are still used for pleasure sailing. The Town of Yarmouth Recreation Department owns and runs the Lewis Bay fleet where most of their 15 boats are used for sail training. Yarmouth also maintains a select group of their knockabouts for their racing program. The Cape Cod Knockabout Association holds an annual regatta each summer which is held at one of the above four locations on a rotating basis. Nearly 20 boats attend this regatta each year. Local fleets are generally increasing their numbers. Cape Cod Ship Building in Wareham manufactures the boat.
