A caisson gate is a barrier used to dam off the open end of a dry dock and is constructed of heavy gauge steel with several tons of ballast in the keel. This deployment is sponsored by The Sportfishing Fund, an organization dedicated to artificial reef building.

Once the structure is fully flooded, it will have no more reason to remain upright and will likely fall over flat.
