The Cape's famous cranberry industry took off in Harwich in 1844, when Alvin Cahoon was its principal grower. Today you'll still find working cranberry bogs throughout Harwich. Three naturally sheltered harbors on Nantucket Sound make the town, like its English namesake, popular with boaters. You'll find dozens of elegant sailboats and elaborate yachts in Harwich's harbors, plus plenty of charter fishing boats. Each year in August the town pays celebratory homage to its large boating population with a grand regatta, Sails Around the Cape.
