A man-of-war's boat, resembling the pinnace, but rather smaller; it is carvel-built, and generally rowed with twelve oars. The yawl in the Customs Act is a carvel-built vessel of the cutter class, but having a jigger or mizen lug, the boom-mainsail being curtailed, so that its boom traverses clear of the mizen-mast: used also by yachts. Also, a small fishing-vessel.
