Abstract
A rescue device adapted to be thrown long distances through the air with the rescue device having a first asymmetrical-annular member having a cross sectional shape in the form of a airfoil with the outer peripheral edge forming a trailing edge of the airfoil and the inner peripheral edge forming a leading edge of the airfoil and a second asymmetrical-annular member having a cross sectional shape in the of a second airfoil with the outer peripheral edge of the second member forming a trailing edge of the airfoil and the inner peripheral edge of the second annular member forming a leading edge of the airfoil with the two members coacting to allow the rescue device to be thrown accurately over long distances with the rescue device including a set of spacers to hold the first asymmetrical-annular member and the second asymmetrical-annular in a spaced apart parallel relationship to allow a line located between the asymmetrical-annular members to unwind therefrom as the rescue device is thrown to a person in distress.
