Before modern technology, how did sailors avoid dangerous rocks and shallow waters where lighthouses could not be built? Step aboard a lightship, a small but incredibly sturdy vessel designed to drop anchor and stay exactly in one spot, no matter how bad the weather gets. Join a dedicated crew, and their brave ship cat, as they live and work on the open ocean. Walk from the bow to the stern, listening to the loud blast of the foghorn and watching the brilliant beam of the ship's massive light pierce through the dark night. Experience the daily routines and thrilling storms faced by these steadfast sailors. This fascinating journey shows you how a relatively small ship held its ground through crashing waves and howling winds, standing as a bright, floating beacon of safety for all the larger ships traveling across the sea.
