Kogyo Maru

The Kogyo Maru, a freighter of roughly 130 m sunk in the September 1944 strikes, lies on her starboard side with her cargo still legible: holds full of construction materials for Japanese airfield works, including cement bags fused into stone, stacked framing, and tracked equipment that divers universally describe as the bulldozer. Swimming the tilted holds feels like touring a hardware depot mid-earthquake. Outside, soft corals and hydroids fuzz the port rail, sweetlips hold under the counter, and squid often hang off the masts. Penetration routes are roomy by Coron standards, though silt and angle still demand care.

您此行的高光时刻: Cargo holds with cement and machinery, readable wartime purpose, comfortable side-lying swim-throughs

地形地貌: Hull on its starboard side on sand around 34-36 m

危险因素: Depth on the sand, silt in the holds, and rotated orientation that confuses navigation.

保育: The cargo is the museum; prying anything loose is both illegal and vandalism.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
