A control system for a towed object (1, 6, 20, 30, 50) in or on a body of water comprises one or more towing members (3) extending between the object (1) and a towing vessel (2). One or more ballast members (4) are movably connected to respective ones of the one or more drag members (3) and are movable at least a certain distance along its respective drag member in a controllable manner. The towed object (1) can be controlled by moving one or more ballast members (4) on the tow member (3) in order to control the catenary (c) of the tow member (3). The individual ballast members (4) may be individually manipulated to correct, maintain, or otherwise alter the geometry of the trawl.
一种用于在水体中或在水体上的被拖引物体(1,6;20;30;50)的控制系统包括在物体(1)和拖引船只(2)之间延伸的一个或多个拖引构件(3)。一个或多个压载构件(4)被可移动地连接到所述一个或多个拖引构件(3)中的相应拖引构件,并且可按照可控方式沿着它的相应拖引构件移动至少一定距离。通过在拖引构件(3)上移动一个或多个压载构件(4)以便控制拖引构件(3)的悬链线(c),被拖引物体(1)可以被控制。个体压载构件(4)可以被个体地操纵以便校正、保持或者以其他方式改变拖网的几何形状。
