[ARC5] Testing battleship radios

Nope.  I'm referring to the white trails that extend from the bow backwards on only one side as noted in the picture, indicating side movement to this meager old brain.  

Just sayin'

  If you mean the white water under the guns, that is an effect caused by
  the gun blast, and is surface only.

  The actual linear motion is calculable from the Conservation of Momentum,
  and a moded of how the ship moves through the water in the direction
  opposite to the gunfire.

  The rolling is calculable from the Conservation of Angular Momentum and a
  roll model.

  Depending on how the guns are aimed, there will be pitch and yaw effects too.
