Delta Marine is a Seattle-based American shipyard producing long-range displacement yachts in fibreglass and steel from 30 to over 90 metres since 1973. The yard is known for interior craftsmanship and structural engineering that prioritises reliability on extended offshore passages, producing vessels that cruise in comfort across ocean distances while maintaining a high standard of interior finish. Harbour Island provides a focused and intimate charter setting for Delta Marine yachts, with the protected western harbour offering calm anchorages well suited to the deep-keeled long-range hulls the yard typically produces. Valentines Marina handles alongside berths for visiting vessels, with provisioning available from North Eleuthera airport nearby. The three Delta Marine yachts available in this region deliver the yard hallmarks of refined American interiors, comprehensive stabilisation and generous fuel tankage. Weekly charter rates range from 100,000 to 350,000 euros. The advance provisioning allowance of approximately 30 percent covers fuel, food, marina fees and beverages. December through April is peak Bahamas season with settled northeast trade winds and the best water clarity for swimming and snorkelling. Pink Sands Beach on the Atlantic shore is the defining Harbour Island excursion, with Dunmore Town dining and the uninhabited Royal Island anchorage completing the programme for guests spending a week in this corner of the northern Bahamas.
