Nathan Clifford, The Merrimac (81 U.S. 199) — Opinion of the Court
“ State pilot laws which compel the owners of vessels to pay half-pilotage in cases where the pilot offers his services and they are refused, where the law is not enforced by any penalty, are not regarded as compulsory, and therefore the fact that the vessel was in charge of a pilot under such a law at the time of the collision is no defence to a libel for damages, if it appears that the collision was occasioned by negligence or unskilful navigation. ”
