Nashua Navy Tug (Wreck) is a purpose-sunk Navy tug off Oahu that sits on sand and functions as a classic artificial-reef wreck. The holds and openings make it a compact but interesting boat dive for trained wreck divers, with marine life around and inside the structure and enough swim-through potential to reward careful buoyancy control.
