(made in 1981)
The Marauder is a new double surface glider manufactured by Gold Marque Sports in Yorkshire. The tips float up under load making for easy landings and by clever sailmaking are 'cupped' to exhaust the high pressure air behind and downwards to delay the tip vortices which normally occur inboard of the tips, so cutting down the effective span. The machine has no vertical keel pocket, but rather a horizontal one which allows the keel sideways movement at the rear. Vertical surface behind the centre of pressure is provided by a fin which is attached between the king post and the back-stay wire.
