Safety notes

Serious dive: many holds contain live munitions and ordnance - do not touch or disturb. Wreck penetration is an overhead environment (silt-out, entanglement, entrapment risk) and the wrecks are war graves to be treated with respect. Remote location - factor in evacuation/chamber access and dive conservatively. Deep profile with penetration options - trained/deco divers only.
