1 A fishing vessel which, as its name suggested, was probably used for line fishing. A development of the original ketch, it was a short, tubby little vessel with main- and mizzen-masts, originally square rigged on the main and with a small topsail above a fore-and-aft-rigged sail hoisted on a gaff on the mizzen. It usually set two jibs on a high-steeved bowsprit, and early in the 18th century it became a distinct type of vessel in its own right, as opposed to the generic ketch. The rig was much favoured for Dutch fishing craft.
2 The name is also used, slightly contemptuously, for any vessel when it grows old and slow, or has perhaps come down a bit in the maritime world.
