Abstract
Disclosed is a water-surface target towed by a mother ship which comprises a towed member running underwater with a ballast weight suspended therefrom, a target pole set up on the top of the towed member, and a stabilizing plate attached to a position above the waterline of the target pole at an angle of incidence. The water-surface target can be used even under bad conditions and towed at a high speed, e.g. 30 knots, due to the towed member being capable of continually maintaining stability underwater.
