Boat Slips, Moorings & Storage in Chatham
Seasonal and transient dockage on the southeast “elbow” of Cape Cod — slips, moorings, and rack & dry storage with fast, deep-water access to Nantucket Sound, the Atlantic, and the region’s best fishing and cruising grounds. Voted the best marina in Chatham for 10+ years.
Our protected basin offers seasonal slips for boats up to 55 feet, with power and water available. Seasonal slip holders get priority access to our fuel dock, service department, and launch — plus a friendly, family-run atmosphere. Space is limited and fills early each spring, so reserve ahead. Contact us for availability, slip sizes, and seasonal rates.
Rental moorings in the Chatham Harbor area with skiff and launch access to your boat. Moorings are an economical option and are always in high demand — the earlier you reserve, the better your chances of a spot for the season.
Dry rack storage keeps your boat clean, secure, and ready to launch all season. Our crew handles the launching and hauling — just come down to the marina and we’ll have your boat in the water within moments. No trailering, no ramp lines. Ask us about in-and-out rack service and off-season storage.
