About Wianno Senior

The Wianno Senior is a 25-foot gaff-rigged sloop that is raced and sailed principally in Nantucket Sound, although the Senior can be found in waters between Maine and Maryland, as well as in Italy. Racing fleets compete out of yacht clubs in Osterville, Hyannis/Hyannis Port, and Bass River. Racing is organized during these clubs from mid-June to Labor Day, and the class championship is raced during three weekends in July where we typically have more than 20 boats competing. Many members of the class enjoy the Wianno Senior for day sailing as well as racing, as the centerboard design permit the boat to safely navigate the shallow waters of the Cape.
