Olympia Maru

The Olympia Maru, a freighter in the 120 m class from the same September 1944 catastrophe, is the fleet's crowd-pleaser: shallow enough for relaxed bottom times, big enough to feel like an expedition, and colonized to the waterline of its former life. Batfish escort divers along the hull in loose formation, glassfish pour out of companionways in silver smoke, and scorpionfish upholster the winches. Holds and engine spaces offer straightforward guided penetration lines with visible exits for those with training. As an introduction to what Coron does, most guides start people here or on the Okikawa, and few argue.

您此行的高光时刻: Batfish escorts and glassfish clouds, forgiving depths, an ideal first Coron wreck

地形地貌: Hull on its side on sand around 25-30 m

危险因素: Silt and sharp edges; easy to overstay on the deeper sand line.

保育: Same protections as the rest of the 1944 fleet; the growth on the hull is decades old and irreplaceable.
