Below are the questions and answers for last month's Navigation Contest.
- The screw-pile lighthouse marked an important architectural development for lighthouses in the Chesapeake Bay and along the Carolina coasts. It was designed for use in waterways with mud banks and shifting sands. The soft bottom allowed wrought-iron piles to be inserted to support the lighthouse structure. It was quick, easy and inexpensive to construct and was a significant improvement over the straight pile lighthouse. The screw-pile was generally a complex hexagonal structure that sat on six to eight outer piles and one central pile, which were screwed in place. One of the most famous of the screw-piles was the Thomas Point Shoal Light built in the Chesapeake Bay. It has been called "the finest example of a screw-pile cottage anywhere in the world." What famous Irish engineer invented this type of construction in the 1830s?
C. Alexander Mitchell
