The captain of Norwegian sailing ship the Squando, which sailed through the Golden Gate in 1890, discovered that his wife was having an affair with the first mate. He was willing to forgive her in exchange for retribution. So, the captain’s wife got the first mate drunk one night and as she held his hands behind his back, the captain burst through the door with an axe and cut the first mate’s head off. The body was floating in the bay the next day. The captain, his wife, and the head, were nowhere to be found.
Mysteriously, the next three captains were murdered by the crew. The Squando was taken back to New Brunswick where it was docked but no guards would stay on it as they all claimed to see a bloody headless man roam the ship at night. The ship was eventually demolished for salvage. On moonless nights, when the fog hovers in really low over the bay, you might see an old three-masted ship in the water sailing from point, to point, to point -- almost as if it’s lost its heading.
