United States Lightship LV-87
 The United States Lightship LV-87 (Ambrose) is a lightship built 1907 and served at the Ambrose Channel station until 1932. She would be the first lightship to serve in the relocated position nearer the center of the channel. In 1921 would have the first radio beacon installed in the United States. This greatly assisted ships navigating the congested Ambrose Channel in dense fog. She would also be the last steam-powered vessel to hold the Ambrose Channel post.
