SANIBEL ISLAND, FL (CNN) - A historic ship from World War II will be commemorated in an untraditional way.
Crews sank the USS Mohawk off the coast of Florida's Sanibel Island Monday in order to make it a reef in the Gulf of Mexico.
It is the first memorial reef dedicated to all U.S. veterans.
The 165-foot Coast Guard Cutter Mohawk is the last remaining ship of the Battle of the Atlantic in the 1940s.
Artifacts are hidden aboard the ship, including an 18th century rum bottle with a treasure map inside. The ship also has a case of aged Caribbean rum within it.
The first divers to find the items will get to keep them.
