Site description

The sunken remains of the Mystic Isle lie undisturbed beneath the waves near Virginia Key. This maritime relic, once a vessel of purpose and adventure, now rests upright on the ocean floor. Its hull, punctuated by a sizable automobile opening just below the wheelhouse, beckons to intrepid divers. Descending into the depths, you’ll find the Mystic Isle’s secrets unfold. Swim through the yawning aperture, and the wreck reveals itself—a silent testament to its storied past. Marine life has claimed it as their own, weaving through rusted metal and forgotten chambers. The play of light and shadow dances across the vessel’s surfaces, creating an eerie beauty. But the underwater tableau doesn’t end there. Just beyond the Mystic Isle’s stern lies another relic—the yacht Esmeralda. This elegant vessel met a different fate, sinking alongside its counterpart. The Esmeralda rests in quiet repose, its timeworn elegance contrasting with the rugged Mystic Isle. For seasoned divers, a unique opportunity awaits. With the right equipment—perhaps a scooter to propel you swiftly through the currents—you can explore both wrecks in a single dive. Imagine gliding from one to the other, tracing the history etched into their corroded frames. The thrill of discovery, the weightlessness of the deep—it all converges in this underwater realm.

Route & typical conditions

Route

Given this dive is done as a hot drop, divers shall first find the wreck - it's a relatively small wreck. After a quick recon, divers may opt to penetrate the wreck. It has two decks to visit where still some benches from this old ferry can be recognized. Be mindful that the best experience for this dives requires penetration. Although there are some coral formations in the outside, the good stuff happens inside.

Typical conditions

This site tends to be dark. Currents can be strong and visibility ranges from 20 to 60 feet (in a very good day).

Wreck history

Mystic Isle historic photo
In 1942, the Burger Boat Company of Manitowoc, Wisconsin, launched the Mystic Isle as a car/passenger ferry. This vessel marked a significant milestone—it was the first all-steel, all-welded passenger boat of its kind on the Great Lakes. Its purpose? To replace the Erie Island Ferry Company’s vessel, the Erie Isle, on the route connecting Catawba Island, Put-In-Bay, and Middle Bass. With accommodations for 335 passengers and 20 cars, the Mystic Isle served its role well. However, over time, ownership changed hands. In 1950, it was sold to the Fishers Island Ferry District in New York. Later, in 1978, the Blount Marine Corporation of Warren, Rhode Island, acquired the vessel through a trade. The Mystic Isle’s journey took an interesting turn in July 1979 when it was sold to Donald Marshall of Fort Lauderdale, Florida. The warm Florida waters became its new home. But fate had more twists in store. By late 1979, the Starboard Navigation Company of Panama purchased the Mystic Isle and converted it into a fishing vessel. However, the vessel’s story took an unexpected and dramatic turn on June 2nd, 1984. The U.S.C.G.C. Diligence seized the Mystic Isle approximately 100 miles northeast of Miami. The reason? It was carrying a load of marijuana—an illicit cargo that forever altered its legacy. And so, the Mystic Isle’s history weaves together maritime innovation, ownership changes, and even a brush with the law, leaving an indelible mark on the waters it once sailed.
