Abstract : The patent relates to a cylindrical body suitable for towing which has a support secured to its surface. The support and cylindrical body have parallel axes with the support extending aft a distance beyond the body. Horizontal and vertical fins of a dimension of 30 percent to 40 percent of the lateral cross-sectional area of the body are secured to the aft end of the support. A drop fin having an area of 20 to 30 percent of the vertical lateral area of the body is affixed to the aft end of the body. An increased separation between the center of gravity and center of pressure is effected by the above plurality of fins.
