Caribsea
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
The freighter Caribsea was torpedoed by U-158 in March 1942 off Cape Lookout; 21 of her 28 crew were lost, among them men whose hometowns faced this same coast. Her broken remains - engine, boilers, and long ridges of hull plate - have become the most reliable sand tiger shark aggregation site in North Carolina. On summer days dozens of the big, ragged-toothed sharks hover in the water column over the wreckage, motionless as parade balloons, threading between divers with sleepy indifference. Baitfish swarm so thickly they form a second surface. Dive it with the respect the loss demands: settle low, move slowly, and let the sharks and the history occupy the water together.
The moment you come for: Sand tigers by the dozen, dense baitfish clouds, a moving chapter of the U-boat war
Topography: Collapsed freighter wreckage - boilers, engine, hull plates - on sand
Know before you splash
Hazards: Fishing line and net snags on low structure; surge over the sand in swell.
Conservation: A casualty wreck dived respectfully; artifact removal is prohibited under state and federal rules protecting these sites.
Nitrox: Worth it here: profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
