A smack was a traditional fishing boat used off the coast of Britain and the Atlantic coast of America for most of the 19th century and, in small numbers, up to the Second World War. Many larger smacks were originally cutter-rigged sailing boats until about 1865, when smacks had become so large that cutter main booms were unhandy. The smaller smacks retain the gaff cutter rig. The larger smacks were lengthened and re-rigged and new ketch-rigged smacks were built, but boats varied from port to port. Some boats had a topsail on the mizzen mast, while others had a bowsprit carrying a jib.
