About Outermost Harbor Marina

Voted the best marina in Chatham the last ten years running, Outermost Harbor Marine is located on the “elbow” of Cape Cod, offering a rare and exciting perspective on the natural beauty that Cape Cod has to offer. Set back in a quiet cove with views of the open Atlantic, our clean and modern marina offers a complete boating experience for our members and guests. Our team of marina personnel, service technicians, and captains deliver just that. From new boat builds, to captain’s lessons, to fixing a leaky dinghy; we are knowledgeable and happy to help.
