Dive Site Overview
The SS President Coolidge, a former luxury liner transformed into a troop carrier, met its fate in 1942 near Espiritu Santo, Vanuatu, after striking mines; this magnificent vessel now rests on its port side. It creates one of the world's most accessible and extensive wreck diving experiences, an underwater museum.
Divers can explore various compartments, including cargo holds, infirmaries, and the iconic "Lady," a porcelain relief discovered within the first-class lounge. Due to the wreck’s immense size, exploration is often broken down into specific dives, each focusing on distinct areas. Recreational dives might reach around 30 meters, with some specific explorations extending to 40 meters for advanced divers into areas like Cargo 1 & 2.
Deeper parts cater to technical divers, who can venture to the engine room at 45 meters, the first-class swimming pool at 55 meters, and the stern between 60 and 70 meters.

Night dives within the cargo holds have been described as particularly captivating, revealing a different aspect of the wreck's resident life. Water temperatures stay consistently warm, generally 26-27°C / 79-81°F, providing a comfortable environment for extended bottom times typical of wreck exploration. Visibility is generally good, allowing for appreciation of the wreck's grand scale and intricate details despite its depth.
Dive Difficulty & Safety Guidelines
Ensuring a safe dive on the SS President Coolidge requires careful planning and adherence to advanced diving protocols. Given its considerable depth range, many areas, such as the cargo holds, necessitate an Advanced Open Water certification or higher. Divers exploring beyond 30 meters should possess deep diver specialty training and experience with overhead environments. Technical diving certifications become essential for those aiming to reach deeper sections, like the engine room at 45 meters or the stern at 60-70 meters. Always dive with a reputable local operator familiar with the wreck and its intricacies. Penetration dives, particularly at night into areas like the cargo hold, demand specialized training and equipment. It's crucial to manage gas consumption and decompression obligations meticulously.
