Half Moon Marina is located on Shelter Island in a beautiful tropical setting adjacent to Humphrey’s Half Moon Inn & Suites and Humphrey’s Concerts. With newly renovated restrooms, showers, laundry room and marina gate, we offer a relaxing atmosphere minutes from the airport, marine chandleries, restaurants, cafes and grocery stores. Summer concerts fill the air with light sea breezes or you can enjoy San Diego Bay and the Pacific Ocean, both of which are a short ten minutes from the dock. Either way, you know you have landed in a special place when you come to our marina. Click on the website link below for a slip application, rates and a map.
