The 290' Cormoran lays in 120 feet of water on her left (port) side directly beside the Tokai Maru (which went down in 1943). See the diagram for the exact layout of the two ships.

Read about the history of the Cormoran here.

The easiest way to reach the Cormoran(and dive on two ships from two different wars at the same time) is to follow the midsection hull of the Tokai over the side until you see the Cormoran at 80 feet. The hull of the Cormoran is intact and the first thing you'll see is the after steering deck house.  

You can descend to the propeller shaft and touch both of the wrecks here. The midship section of the Cormoran is intact and the engine room is easily accessible through the skylights, and most of the superstructure is relatively accessible. 

Just behind the bridge there are two open cargo loading doors, and descending into this area leads you to the insides of the ship. Visibility averages 25-60', but can vary due to the tide and ship traffic in the harbor. A good average diving depth to see all of the starboard side would be 80-100 feet.

This wreck is a very good wreck for nitrox divers because of the average dive depth between 80-110 ft.  You can ascend up the side of the Tokai Maru and do a safety stop on the buoy lines attached to the Tokai.

WARNING: DO NOT enter any shipwreck without the proper training and equipment. Six divers have paid the ultimate price of their lives while diving inside wrecks here on Guam.   Do not breathe the air trapped inside the wreck. It can be very toxic.
