This was my Third dive towards my 'Advanced Diver' rating. It was a wreck dive. It is a wreck called the Cement Wreck. I have been told that it was a wooden boat loaded with cement bags that was going from Kwajalein to Ebey. The boat caught fire and sank just off shore ~150 yards or so. There is no wood left from either decay or from the fire. It looks like a bunch of pillows with coral growing all around. The fish seem to love it, the bags did not fall perfectly on top of each other, there are now passages for the fish and the creatures to swim in and out of, almost like little tunnels and caves through out the cement load. The diesel engine is about 6 - 8 feet away. Which is all that is left from the wreck. We saw a very large Manta Ray 8 - 10 foot span.
