Irako

The Irako, a roughly 147 m Imperial Japanese Navy refrigerated provision ship, went down in the air strikes of 24 September 1944 and settled almost upright, largely intact, which is why many rate it the finest wreck in the Philippines. It is also the deepest of Coron's regular fleet: decks around 28-34 m, seabed past 40. Trained wreck divers work the galley spaces and the cathedral-dark engine room, where machinery stands in place under a fur of silt; everyone else patrols the rails among lionfish, grouper, and schooling snapper. Lives were lost when she sank, and guides brief the fleet's wartime dead accordingly.

El momento por el que vienes: Coron's most intact major wreck, famed engine-room penetration for the trained, big fish on a big hull

Topografía: Upright hull on a mud-sand seabed at 42-45 m

Corriente: Usually calm at depth; descents run down a mooring line.

Riesgos: Depth, dark silty interiors, sharp steel, and short no-deco windows; penetration requires training, lights, and a guide who knows the hull.

Conservación: A historic wartime loss: artifacts stay aboard, and operators expect respectful conduct throughout the fleet.

Nitrox: Vale la pena aquí — los perfiles se sitúan en el rango donde el aire enriquecido (nitrox) amplía de forma significativa el tiempo sin descompresión (con la formación necesaria para usarlo).
