- shot record, it is necessary to make a correction for the 
time it took the shot instant to travel from the shot point 
to the shooting ship (see Figure 1). In order to do this 
it is necessary to know the depth of the shot and the dis- 
tance that the ship has traveled from the time the shot was 
thrown over the side to the time it detonated. 
The distance that the ship has moved is obtained

The depth of shot is read directly from the shot record. It
