If field tests of a new vessel-steering are as successful as engineers' calculations and tank tests indicate, the rudder which has been used to guide ships and boats through the water for a thousand years may become as archaic as slave propulsion. The new system is based on "The Magnus Effect", which in simple terms is: If a vertical cylinder immersed in water is rotated, it produces a force at right angles to the direction of the water flow past it. Although this principle has been known since the turn of the century, curiously it has not been applied to vessel steering. Research and development show that the industry has been missing a bet. The new steering system requires only a small amount of power to turn the cylinder, yet produces strong turning forces at slower speeds with very little drag. This contrasts sharply with the conventional rudder.
