The Olympia Maru, 160 m (528ft) long, 10,045 gross tons, was sunk on 9 October 1944 by US aircraft. It sits almost level, with a slight list to port, pointing 330 degrees (compass bearing), with the bow broken off in 26m (86ft) of water. The main deck is at 16m (53ft). A good wreck for penetration and wreck-diving courses, the Olympia Maru has everything. It is well covered with good corals, particularly very large lettuce corals, sponges and shoals of fish including fusiliers, turtles, snappers and batfish, plus the ubiquitous lionfish and scorpion fish.
