it is very much less extreme than on traditional Bermudian designs, with lower, vertical masts, shorter booms, omitted bowsprits, and much less area of canvas. The term Marconi rig was first applied to the tall Bermuda rig used on larger racing yachts, such as the J class used since 1914 for the America's Cup international yacht races, as - with the many supporting cables required - it reminded observers of Guglielmo Marconi's mast-like wireless antennas (Marconi's first demonstrations in the United States took place in the autumn of 1899, with the reporting of the America's Cup at New York). Although sometimes treated as interchangeable with Bermuda rig generally, some purists insist that Marconi rig refers only to the very tall Bermuda rig used on yachts like the J-class.
