Best for advanced divers, 18-36m, boat entry, strong current.
The USCG Duane is a 99-metre decommissioned Coast Guard cutter resting upright on a sandy bottom at 36 metres. The wreck's superstructure rises to approximately 18 metres, allowing the full profile to be visible in typical conditions. This site is intended for advanced divers due to significant depths, strong currents, and potential entanglement hazards within the overhead environment. Visibility ranges from 21 to 36 metres. Access is by boat only, and divers should use the mooring line for descent. The site features a range of facilities including air fills, rinse stations, and guided tours provided by local dive shops.

Current on the Duane can run hard enough to make descending the mooring line mandatory rather than optional, so clip in and pull yourself down rather than free-falling to the wreck. Time your dive to the slack between tides if your operator allows flexibility, as even a modest reduction in flow makes working the deeper sections and interior passages significantly safer.
