About SS Mauna Loa
The Mauna Loa was struck during the first wave of the attack and settled near the Meigs in the outer harbour. The wreck is more broken than its larger neighbour but remains substantial, with the hull lines, hatches and machinery visible at depths of 18 to 22 metres. The site is typically dived on the same day as the Meigs during a single slack-water window.
