The largest or long boat of a ship of war. Others of greater size for gunboats are used by the French, Spaniards, Italians, &c., in the Mediterranean. A launch being proportionably longer, lower, and more flat-bottomed than the merchantman's long-boat, is in consequence less fit for sailing, but better calculated for rowing and approaching a flat shore. Its principal superiority consists in being much fitter to under-run the cable, lay out anchors, &c., which is a very necessary employment in the harbours of the Levant, where the cables of different ships are fastened across each other, and frequently render such operations necessary.
