USCGC Spar
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 — treat everything here as planning ranges.
The Spar spent a working life tending buoys and breaking ice for the Coast Guard - she was among the cutters that circumnavigated North America via the Northwest Passage in 1957 - before being sunk as an artificial reef off Morehead City in 2004. She sits upright and compact, small enough to tour thoroughly in one dive: deckhouse, mast, and open holds, all claimed within a few seasons by the local cast. Sand tigers now hang in her lee and drift along the rails, often in company with the schools of spadefish and amberjack that use her as a mid-ocean landmark. For divers building offshore experience, she is the friendliest of the Crystal Coast's shark wrecks.
The moment you come for: An upright, easily navigated cutter with resident sand tigers
Topography: 180-ft Coast Guard buoy tender upright on sand
Know before you splash
Hazards: Current at the mooring; entanglement points around rails and rigging remnants.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
