Line charge deployment apparatus

An apparatus for use with a moving watercraft, comprising:

• a rigid arm having a first end and a second end with said first end being coupled to the watercraft aft of said second end with respect to a direction of travel of the watercraft, said first end being rotatably coupled to the watercraft to permit rotation of said arm about said first end, said vertical plane of rotation being aligned with said direction of travel, wherein said second end can extend into the water as said arm moves in said vertical plane of rotation, and wherein said arm initially rotates in said vertical plane of rotation due to gravitational forces and secondarily rotates in said vertical plane of rotation due to hydrodynamic forces can acting on said arm;
• a weight;
• and
• a releasable coupler for coupling said weight to said second end and for releasing said weight in the water.

An apparatus for use with a moving watercraft;

• comprising:
• a rigid arm having a first end and a second end with said first end being rotatably coupled to the watercraft to permit rotation of said arm about said first end wherein, at deployment, said second end is positioned forward of said first end with respect to a direction of travel of the watercraft such that gravitational forces and hydrodynamic forces act on said arm to cause rotation of said arm about said first end;
• a drogue;
• a releasable coupler for coupling said drogue to said second end and for releasing said drogue in the water;
• and
• a plurality of line charges tethered in sequence to one another and tethered to said drogue wherein said plurality of line charges are pulled one-by-one under the surface of the water after said weight is released from said second end.
