The Long Beach Marina, which includes Alamitos Bay Marina, Long Beach Shoreline Marina (Downtown Marina), and Rainbow Harbor / Rainbow Marina, truly has one of the greatest locations in California, if not the United States, for boat slip mooring. Boats are protected by a series of offshore breakwaters and by a natural south-facing bay. Our boating public appreciates the rapid access to open water, prevailing winds and close proximity to Catalina Island. Sailing conditions in Long Beach are practically perfect year round. That is why Long Beach has been, and continues to be, home of the Congressional Cup, Transpac and Olympic trial races.
