Irako Wreck, Coron Bay

A Japanese refrigeration ship sunk in 1944, upright in 42 m and the deepest of the Coron wrecks.

Activities: Scuba · Technical

The Irako sits upright on the bottom of Coron Bay, sunk in the American air raid of September 1944. The deck is at about 28 m and the sand at 42, which puts the whole dive at or past recreational limits and makes it a nitrox or technical dive in practice. Visibility inside is poor and the silt is fine, so penetration is for divers with wreck training and a line. The engine room is the reason people come.

Boat from Coron town, Busuanga; about 40 minutes.

Before you get in

Going inside a wreck is an overhead environment: silt can take the visibility in seconds, and there is entanglement. Swimming the outside of it is a different dive.
Deeper than recreational limits. It carries a decompression obligation and gas planning, and is not a dive to plan without that training.

Taken from this site’s recorded depth, type and current, and nothing else. An empty list is not a safe site — the sea on the day, the local geography and the boat traffic are not in it. The briefing on the spot comes first.

Forecast heights against mean sea level. Real tides in a bay, a harbour or over a flat can differ — check an official tide table before you get in.

Only wave height and wind are scored, because those are what close a boat ramp or a shore entry. Water temperature is reported and never scored: 12°C is an ordinary dive in a drysuit and punishing in a 3 mm, and a number that cannot see your suit has no business marking it down. Stars do not decide whether you get in — you and your guide do, on the day.
