The Great Lakes Singlehanded Society is an organization established for the perpetuation of the sport of solo sailing. It is one of the few organizations where no amount of money will purchase a membership - only by successfully completing a Port Huron to Mackinac, Chicago to Mackinac, Sault Ste. Marie to Duluth, the Lake Erie Solo Challenge, or the Lake Ontario 300 Solo Challenge is lifetime membership conveyed by the Society. Pick a Great Lake, and we are there to accommodate you!
