Irako

Japanese refrigeration ship
displacement 9,570 tons
length 147 meters
Location: At the mouth of Coron Bay

Probably the best wreck dive in the Philippines. The Irako is quite intact and because of the good visibility you know you are on a big shipwreck. Big groupers, schools of tuna and yellow fin, lion fish and scorpion fish live around this wreck. Two sea turtles live in the crumpled and folded metal of the superstructure. There is a beautiful deep penetration through the engine room for trained, experienced and properly equipped divers.

Irako usually has the best visibility of all the wrecks in Coron Bay.

This dive is best made at deck level while breathing 32% Nitrox for a 50% increase in allowable bottom time. Penetration of the interior would require 30% or 28% Nitrox depending on which deck level you wish to swim through.

Max depth: 43 meters on the bottom, deck level at 28 to 35 meters. Recommended certification level: Advanced Open Water Diver, Deep Diver Specialty, Wreck Diver Specialty.

Okikawa Maru

Japanese tanker, 168 m long
Location: Busuanga Island, 2 miles south of Conception

In length, width, and volume the largest of the Coron wrecks. At this depth you may be able to make an hour-long dive. If the Irako isn't the best wreck dive in the Philippines then the Okikawa Maru certainly is! This wreck is totally covered with beautiful corals and offers a large variety of marine-life. The deck is between 10m and 16m and is good for wreck dive beginners. There are many penetration possibilities for advanced wreck divers including penetrating up the propeller shaft from the outside of the ship all the way into the engine room. Strong tidal currents often affect this wreck. Diving in strong currents lets you see the most fish. At the bow you can see the resident three legged turtle and a school of snappers holding position into a slight current. Large fish shelter out of the current behind crumpled metal and inside of the deckhouses.There is also a large resident grouper near the bottom.

This dive is best when made while breathing 36% or 38% Nitrox for a 75% increase in allowable bottom time. Dives in excess of one hour are common on the Okikawa Maru.

Max depth: 26 meters on the bottom, 10 to 16 meters on the deck. Recommended certification level:

1. Diving outside the deck without a current. Open Water Diver
2. Diving with a current. Advanced Open Water Diver
3. Diving with a strong current. Experienced Advanced Open Water Diver
4. Penetration dive. Wreck Diver Specialty

Akitsushima

Japanese Seaplane Tender 118 m long
Location: Between Culion & Busuanga Islands, near Manglet Island.

The Akitsushima is a very big warship that lies on her port side. She was hit near the stern where the flying boat rested on the metal tracks and sank immediately. The ship was almost torn into two pieces. The flying boat disappeared. Only half of the metal on the starboard side and half of the metal on the bottom of the ship kept the stern from separating from the rest of the ship. The internal damage is impressive.

The crane used for lifting the seaplane out of the water is intact. The crane is lying on the sandy bottom and attracts schools of giant batfish and barracudas. One mounting of a 3-barreled AA (antiaircraft) gun is still present at the front of the flying boat tracks. This is a fascinating dive where you can see giant groupers, schools of barracuda hiding under the bow, and yellow fin tuna.

Due to depth and metal hazards within, no swim throughs are allowed without wreck diver certification. Wreck divers can make an impressive penetration into the engine room to see the four engines. The gears and machinery for operating the crane are the main objects of interest for a penetration into the stern.

This dive is best made while breathing 31% or 32% Nitrox for a 50% increase in allowable bottom time.

Max depth: 35 or 36 meters, average depth about 26 to 28 meters. Recommended certification level: Advanced Open water Diver. For penetration: PADI Wreck Diver specialty.

Kogyo Maru

Kogyo Maru was a Japanese freighter carrying construction materials for building a runway for the Japanese war effort in the Pacific. Kogyo Maru was built in 1938 and is 158 m long with a displacement of 6,353 tons. Lying on her starboard side in 36 meters of water the Kogyo Maru offers swim throughs into all six holds and through the engine room and bridge area. Kogyo Maru's second hold contains an incline of cement bags which tumbled as the ship sank. A small bulldozer draws your attention as you swim into the hold. Complete but encrusted, you can imagine the operator sitting in the seat and working the control levers to carve a runway out of a tropical island. Engrossed in the bulldover you might fail to look up the incline of cement sacks and so miss the tractor and air compressor perched above it. Take the time to swim up and look at both pieces and see how many of the engine parts you can identify. It's complete. Check out the metal wheels on the tractor. Coming out of the hold swim up the front mast, now horizontal, and on your left side. At the top of the mast look at the crow's nest and imagine what a lookout would experience when perched 30 meters above the water in a Japanese winter storm. Swim back over the deck to the bridge and engine room below it. Enter both from the stern side for easier access. Swim through the cavernous engine room and look at the hardware then out through the bridge. If air is low go up to the port side of the bridge and look at the soft corals growing there and the fish life living on this artificial coral reef at 22 meters. If you have enough air continue below deck level to the stern looking at all of the deck hardware for moving cargo and working the ship. Pass around the stern and then go forward over the port side to return to the mooring line. You pass over hard and soft corals covering the side of the ship. On this dive keep your head and eyes moving like a fighter pilot's to see the school of barracuda which will swim by. If you only look at the Kogyo Maru you will miss the barracuda.

This dive is best when made while breathing 31% or 32% Nitrox for a 50% increase in allowable bottom time. If you dive the Kogyo Maru with a 100 cubic foot tank of Nitrox 32 you have enough gas mixture and a long enough No Decompression Limit to cover the whole ship on one dive.

Max depth: 34 m, average 24-26m Recommended certification level: Advanced Open Water Diver, Wreck Diver Specialty.

Olympia Maru

Japanese Freighter sitting upright with a length of 122 meters
Location: Coron Bay

A very good dive spot with a variety of marine life. Large shoals of banana fish, giant bat fish and giant puffer fish, especially around the mast, bow and stern. Easy penetration at the cargo rooms. It offers a good opportunity to discover wreck diving.

This dive is best when made while breathing 36% Nitrox for a 75% increase in allowable bottom time.

Max depth: 28-30 meters, deck level 18-24 meters. Recommended certification level: Advanced Open Water Diver, Wreck Diver Specialty.

Japanese Freighter (Taiei Maru?)

Japanese freighter 137 meters long, lying on its starboard side
Location: Coron Bay

This is a beautiful wreck dive site where you can observe groupers, sweetlips, occasionally turtles and sea snakes. Hard corals cover the port side, which is only 12 to 16 meters below the surface. See if you can find the two resident trumpet fish that hang out half a meter over the part side corals. Many scorpion fish hang out around the wreck area. Keep your eyes open and stay neutrally buoyant!

The big cargo rooms and the engine room allow easy penetration of this wreck for Wreck Diver Certified divers. If you dive from 10 AM to 2 PM on a sunny day you get a cathederal like effect from the beams of sunlight entering the cargo holds through the holes in the port side. The two massive boilers in the center of the ship are a big attraction on this dive. You can pass behind the boilers and see the damage resulting from one of the bomb strikes that disabled the ship. It is possible to do a swim-through and pass from bow to stern without exiting the ship.

This dive is best when made while breathing 36% or 38% Nitrox for a 75% increase in allowable bottom time.

Max. depth: 25 meters, average about 15 meters. Recommended certification level: Open Water Diver, Advanced Open Water Diver, Wreck Diver Specialty
