Site details

The 301-ft wooden bulk carrier Frank O'Connor caught fire and sank on October 3, 1919, while carrying 3,000 tons of coal, settling in 65 ft of water about 2.6 miles north-northeast of Cana Island. Its museum-quality triple-expansion steam engine and boilers rise more than 20 ft off the bottom, making it one of Door County's signature wreck dives. Two WHS seasonal mooring buoys mark the bow and engine.
