Corsair

Corsair is a deep wreck dive off the east side of Oahu near Maunalua Bay centered on a largely intact, upright Vought F4U Corsair fighter resting on a white sand bottom at about 107 to 110 feet. The aircraft is the site's main attraction, with the cockpit, tailhook, landing gear, and a bent propeller clearly visible, and corals and sponges encrust portions of the wreck as an artificial reef. The site is boat access only and is an advanced open-water dive due to the depth and offshore location. Divers descend a mooring line and should plan dives at slack tide because currents can become moderate to strong. Visibility is usually excellent, often up to 100 feet or more, and water temperatures typically range from the mid-70s to low 80s °F. Divers should carefully plan bottom time and nitrogen management, practice good buoyancy control, use the anchor line, dive with a buddy, and avoid rapid ascents; the primary hazards are the depth and potential for currents. The plane was not intentionally sunk but was ditched in calm seas in 1946 after the pilot ran out of fuel during a training flight. It lies largely intact and upright on the seafloor and has become a popular and iconic advanced wreck dive on Oahu.
