New Barge is a deep, boat-only Oahu wreck built as an artificial reef with an upright barge, internal baffles, and multiple access holes that make it a serious penetration dive for experienced divers. The wreck sits on a slight slope, with Z-block and rubble areas around it, so the real value is the mix of structure, drift potential, and marine life rather than easy sightseeing. Plan it as a controlled wreck dive with clear turn pressures and a conservative current plan.
