Hello Inajira,

I agree with JoeS & Rosencrantz.

As you probably know, the only AOB worth talking about is the 90° (port or starboard perpendicular attack).

Here are some situations to consider:

If you're dead in the water and perpendicular to the target's track (course) the AOB is constantly increasing each moment the target gets closer to your bows.

During a Collision Course (when the target appears to remain at a constant AOB as both vessels proceed toward a collision as their speeds and courses satisfy the conditions for the Law of Sines: a/sin A = b/sin B = c/sin C)

To shoot at a target with an AOB of angles < 60° or > 120° is a waste of time and a valuable torpedo in my estimation, due to the increased chance of a Dud (glancing blow) or Miss (narrower target angle).

The matador doesn't thrust the sword into the bull unless it's for a clean kill. However, I know we all salivate for the chance of many success pennants hung from the ASR as we return to port.

My suggestion is to learn to do it by "sailor's eye" rather than "whiz-wheel".

Cpt Dick "Killer" O'Kane, when the XO aboard the Wahoo, practiced constantly in the Wardroom with a model ship on a "lazy susan" made by the COB. O'Kane would look at the model through a reversed pair of binoculars and call off the AOB, as a shipmate would turn the "susan". He was never off more than 5°.

Cheers,
