Seaplanes Launched From Deck of Ship on Canvas Slide
MAIL-STEAMERS not equipped with expensive catapults for launching airplanes at sea will welcome the invention of the Kiwull watersail, so named after its inventor, which is shown in operation in the above drawing. The invention is simple, consisting of a length of canvas 100 feet long and 32 feet wide which is unrolled from the stern of the ship, as shown, to form an incline down which a seaplane can be lowered to the water. The canvas is held taut by water pulling against a “drogue” or net at the trailing end. Seaplanes can also return aboard deck by this means.
