THE AMBROSE LIGHT VESSEL AND AN OCEAN LINER This light vessel is anchored off the entrance to New York Bay. Ocean passages are reckoned to or from this ship. "Light-ships are placed in locations off the coast where it would be impracticable or needlessly expensive to build a lighthouse, and they usually mark the approach to a port or bay, or the outer limit of an offlying danger. They are also sometimes used in inside waters. They may be moored in, the channel or close to it, and they have the advantage over most lighthouses, that a vessel may steer directly for them without danger so long as collision with the light vessel is avoided, and also that they may be moved and moored in another position when change of conditions or necessity requires. On the other hand, a light vessel is more expensive to maintain, and there is the possibility of its being driven from its station, though this is reduced in recent years by improved vessels and moorings" (see page 41). THE NANTUCKET LIGHT VESSEL, MOORED- IN THE ATLANTIC 41 MILES FROM LAND Most of the transatlantic vessels steer for this vessel. "Life on a light-ship is somewhat dreary, but not without excitement. During every fog the crew on Nantucket ship know that numerous vessels are headed directly for them, and in a storm, anchored as they are in the open sea, they may be far from comfortable. The men in turn are allowed liberal leave ashore. There are often serious difficulties in getting coal and provisions to the ships on exposed stations, so that it is necessary that they carry sufficient supplies to last over stormy periods" (see page 43).
