PT boat with crew.
Everything is a blur as a possible enemy ship is sighted.
Break radio silence and send a signal to HQ.
PT boats often were in place to observe the enemy.
Planes can scramble and be on the enemy ship in minutes.
In the meantime the PT boats can attack, watch the action from afar if the ship is not within striking range.
PT boats have limited fuel and so their range is not long.
Sometimes you have done you job if you have only observed and reported those observations.
