A one-time drug-smuggling ship is now a South Florida's artificial reef. U.S. Customs seized the 165-foot MV Princess Britney during Operation River Walk when they say they found 156 kilograms of cocaine hidden underneath the deck of the engine room. The MV Princess Britney was sunk around 3.5 miles off the coast of Key Biscayne. The ship came to rest on a sandy bottom about 90 feet below the surface. Great dive for photographer!
