Dive Site Overview
Imagine descending upon a colossal ocean liner, reborn as an underwater habitat, offering unparalleled exploration opportunities. Soon to replace the USS Oriskany as the world's largest artificial reef, the 990-foot SS United States will provide multi-level diving for all skill levels.
Reaching 55 m (180 ft) at the seafloor, divers can explore everything from the top deck, accessible around 17 m (55 ft), down into cavernous hallways, vast cargo holds, and intricate bridge structures where the propellers once churned. Its sheer length allows for extensive exploration routes, potentially revealing new sights on every expedition. Okaloosa County purchased this vessel to create essential marine habitat where natural reefs are scarce offshore Destin-Fort Walton Beach.
Visiting here allows for repeated dives; experts predict one could return 100 times and not see the same area twice, ensuring continuous discovery. This project also significantly boosts regional tourism and preserves the ship's storied legacy, preventing its journey to the scrapyard.
Best Time to Dive
Optimal diving conditions at Okaloosa County Lap Site C generally span from May through September, consistently yielding 'Good' dive scores. During these months, average air temperatures range from a comfortable 24.3°C (76°F) in May to 29.1°C (84°F) in August. Wave heights are typically lower, averaging between 0.68 m (2.2 ft) and 0.92 m (3.0 ft), accompanied by calmer wind speeds from 23 to 26 km/h (14-16 mph). Rainfall, while present, averages moderately, peaking at 6.45 mm (0.25 in) in September. From October to April, 'Moderate' dive scores are more common. Air temperatures cool, reaching lows of 13.8°C (57°F) in January, and conditions may include higher wave heights, up to 1.34 m (4.4 ft), and stronger winds, such as 36.2 km/h (22.5 mph) also in January. Specific water temperature data for the site is not consistently reported, so divers should prepare for cooler conditions outside the peak season.

Dive Experience & Conditions
Beginning your descent, the sheer scale of the SS United States quickly becomes apparent. A top deck, lying around 17 meters (55 feet), offers an immediate expanse for recreational divers. As you navigate deeper, the structure promises cavernous hallways, vast cargo holds, and intricate bridge sections awaiting exploration. Maximum depth at the seafloor is approximately 55 meters (180 feet), where the propellers were originally situated, making it suitable for divers with varied experience levels, from advanced open water to technical divers. Penetration opportunities will be extensive, requiring proper training and equipment. Visibility will be a key factor influencing ease of navigation through the ship's interior. Multi-level diving allows for extended bottom times on shallower sections and progressive exploration as skills develop.
Dive Difficulty & Safety Guidelines
Before planning a dive on this extensive artificial reef, experienced divers should prioritize thorough preparation and adherence to established wreck diving protocols. Once deployed, the site will present an expansive and complex wreck structure, demanding meticulous buoyancy control and careful finning to prevent disturbing sediment, which can quickly reduce visibility. Okaloosa County followed strict federal and state guidelines, including Environmental Protection Agency and Army Corps of Engineers rules, during the remediation process to ensure the ship's integrity and safety for both divers and marine life. Notably, explosives were not authorized for its sinking. Divers intending to explore the interior must possess appropriate certifications and consider the buddy system paramount for safety in such intricate environments.
