The Vessel and Her Loss
The four-masted schooner Harry P. Knowlton, freed from ice in the Hudson River and pressing to make up lost time, was under full sail in Block Island Sound on the night of 11 February 1907 when she struck the passenger steamer Larchmont amidships during a fierce winter gale. The collision tore open the Larchmont's hull, and both vessels were destroyed; the Larchmont sank quickly with roughly 150 people aboard, most of whom died of drowning or exposure in the freezing seas. The disaster became known as one of the worst in Rhode Island's maritime history.
