The calls for the various types of boats follow: BOAT  CALL BOAT  TYPE Qp0 All  boats Qp1 Admiral's barge Qp2 Chief of Staff barge or gig Qp3 Staff  gigs  or  motorboat Q p 4 Captain's gig Qp5 Boats  under  power Qp6 Boats  under  sail Q p 7 Boats under oar Qp8 to Qp50 Reserved for local assignment by commanding officer Calls  are  usually  assigned  according  to  boat  numbers. An example of a call to own ship's boat is Qp52, meaning own ship's powerboat number 2. To call another ship's boat, the ship's call is placed under the boat call. For example, Qp4Rp6p2 calls the captain's gig of carrier 62. The general recall for all boats to return to their ships is  QUEBEC  hoisted  singly. Figure 5-12 illustrates the recall signal for the captain's gig (QUEBEC over PENNANT FOUR). STEERING A BOAT BY COMPASS LEARNING OBJECTIVES: Describe how to steer a boat by compass. Recognize compass error and describe how to correct compass error. Standard powerboats and landing boats are always equipped with a compass. The coxswain uses this instrument more than any other device in piloting the craft  to  its  destination. Both  the  magnetic  compass  and  the  gyroscopic compass  were  explained  in  Chapter  2  of  this  book; hence, they are not discussed here. The rest of this chapter does, however, explain many of the things you must know about steering a boat by compass. The coxswain must ensure that the compass light is installed and operating for night runs. To follow a compass course, the coxswain leaves the side of the ship, swings around to the bow, and uses either the point C118.49 Figure 5-12.–QUEBEC over Pennant Four. where the anchor chain enters the water or, preferably, the anchor buoy as point of departure. The coxswain then steers the previously given compass course. By this method  the  boat  should  arrive  at  its  destination  with  little difficulty if there is no wind or current, if the compass is in good condition, and if no metal objects (such as tools, or a large steel vessel passed en route) cause the compass  to  deviate. It is necessary for the coxswain to move approxi- mately 100 yards away from the ship before taking the compass reading. The reason is to prevent the magnetic attraction  of  the  ship's  hull  from  influencing  the operation of the boat's compass. Trust your compass. At times you may swear something has gone wrong with it, but that is probably your imagination, not a faulty compass. It is not a good practice to try to make your way from ship to ship by listening for the ship's bells. Sound is deceptive in fog. Sound seem to come from everywhere at once. If you should become lost, you may have to listen for bells to try to find the nearest ship. Never leave your ship without knowing which berth the ship is in. Handle your compass with care so that you can rely on it when you need it. COMPASS  ERROR Two forces make up compass error. They are variation and deviation. Earth is a huge magnet. The north magnetic pole of Earth is over a thousand miles 5-15
