Tug

A steam vessel built for towing; practically synonymous with towboat. Tugs are subject to the ordinary rules of navigation touching collisions. Where a schooner was being towed by a tug lashed to her port side, the fact that the schooner bad a pilot on board did not make the tug the mere servant of the schooner, so as to exempt the tug from responsibility; The Charles Allen, 11 Fed. 319; The Atlas, 93 U. S. 302, 23 L. Ed. 863. A tug is not a common carrier or insurer, and is bound only to reasonable care and skill; The W. II.
