Anchor Windlass Room Lightships were equipped with a unique "mushroom" anchor which extended from the very center of the bow of the ship, rather than from the side of the bow as most ships. This anchor, which does resemble a mushroom, weighs 6,000 pounds. Lightship anchors were secured to the ship by a large Dilok chain, each link weighing 14 pounds. The chain is measured in shots; each shot is 90 feet long. Usually lightships let out 5 to 7 times as much chain as the depth of the water in which they were stationed. There are 5 shots of anchor chain aboard the lightship. Two shots (180 feet) were used on station at Corsica Shoals. These shallow waters, six miles north of Port Huron, were the scene of frequent grounding by lake freighters in the late nineteenth century. The space forward of the Windlass is called the Manger. The name originates from the early days of shipping when livestock was kept aboard sailing vessels so crew members would always have a supply of fresh meat.
