Okikawa Maru

She sits upright with the main deck at around 12 m and the bottom at 26 m, so most of the ship is within an ordinary recreational profile and the limits come from the layout rather than the depth. At 160 m she is the largest wreck in the bay, and two dives is the realistic minimum to see her, which makes it worth agreeing beforehand which end of the ship you are diving.

Penetration runs deep into the hull, down to the engine room and along the propeller shaft, and that part of the dive is dark, tight in places and dependent on training. The easier set piece is at the bow, where the bomb blast opened the hull into a swim-through. Visibility depends on the tide, dropping to 5 m at its worst and reaching about 15 m when the timing is right, and the current over the wreck can occasionally run strong.

Groupers and sweetlips hold around the hull and lionfish and nudibranchs are common on the plating, so the upper half of the ship reads as a reef as much as a wreck. The hard and soft coral on the shallower sections is heavy enough to be the reason for a dive in its own right, rather than a consolation for having already worked through the interior.
