Abstract:

An apparatus is provided for placing, for example, a line charge set under the surface of the water from a moving watercraft. A rigid arm has a first end and a second end with the first end being rotatably coupled to the watercraft to permit rotation of the arm about the first end such that the second end is free to rotate into the water when the arm is not restrained. The second end is positioned forward of the first end with respect to a direction of travel of the water craft. In this way, gravitational forces and hydrodynamic forces act on the arm to cause rotation of the arm about the first end. A releasable coupler couples a drogue to the second end and releases the drogue when the second end is in the water. The line charge set is tethered to the drogue and is pulled into the water as the watercraft continues on its course.
