A word that is something of a rarity which was
coined by Ocean racer design guru, John lllingworth (1903-1980) for a rig which has something of the sloop and
something of the cutter. Only one headsail is set at a time, but there is a
choice of two, one of which is set to the masthead (light weather) and the
other to some lower point on the mast (stronger winds).
