Built in 1919 for the British Admiralty, the iron hulled vessel was a patrol gunboat. Famously it carried Admiral Richard E. Byrd’s American expedition to Antarctica in 1928. She brought supplies to the polar base including the airplanes that made the first aerial flyover of the South Pole. After the expedition, Vamar became a freighter and in 1942 whilst carrying lumber to Cuba she sank under mysterious circumstances while leaving Port St. Joe.

The vessel now rests 4 miles off shore of Mexico Beach and represents one of the many aspects of Florida’s maritime history. Lying under 25 feet of water, today divers can see a large steam engine, bilge keels, and a wide variety of marine life.
