A 180-slip Shelter Island marina in Point Loma, Half Moon Marina accommodates vessels from 20 to 82 feet adjacent to Humphreys Concerts by the Bay at 2323 Shelter Island Drive. Slip fees include water and a dock box with shore power metered per use, while Shelter Island's marine-electronics ecosystem routes through specialty shops such as Shelter Island Marine Electronics that service the basin's full-time and transient vessels. The marina basin draws at least 12 feet at 0-foot mean tide across most slips, and the facility sits roughly ten minutes from the open Pacific through the San Diego Bay entrance, a draft-and-proximity profile suited to cruisers and offshore sportfishers alike. Newly renovated private restrooms, showers, laundry rooms, and a tenant lounge pair with a gated perimeter, with on-water contractor work for slip tenants routed to Point Loma marine specialists such as Sea Monster Marine. The marina adjoins the Humphreys Half Moon Inn hotel complex, Humphreys So Cal Dining & Music restaurant, and Humphreys Backstage Live music lounge -- a combined hospitality footprint unusual for a San Diego Bay boating facility. The most complex coordination the dock handles is accommodating mega-yachts at the 82-foot-class slips during Humphreys Concerts by the Bay summer event nights, when transient reservations, power-draw scheduling, and concurrent vessel docking layer across standard slip operations.
