Abstract
A sloop comprising a mast in the form of an A-frame with its plane athwartships. The luff of the mainsail is supported by a mainstay which is a thin wire or rod running from the apex of the A-frame vertically to a point on deck between the legs of the A-frame. This structure eliminates the turbulence along the leading edge or luff of the mainsail caused by conventional masts, and also permits a headsail to be closely hauled. The A-frame comprises one or more rigid horizontal spreaders and the mainsail boom and a spinnaker pole can be slidably mounted thereon.
