Sunk deliberately, the HMS Vixen was a Royal Navy gunboat launched out of the UK in 1866. After serving her military career, she was supposed to be sold for scrap in Bermuda. However, the military brain trust at the time decided Bermuda needed protective barriers in key spots around the island. The Vixen was scuttled in 1896 near Daniel's Head off Bermuda's west coast.
The HMS Vixen was an armoured gunboat that served with distinction, protecting the Royal Navy Dockyard in Bermuda. After finishing her days as an accommodation hulk for dockyard workers, the Vixen was scuttled off Daniel's Head in 1895, laying in a narrow gap in the coral reef, with the bow just above water.
