normally provides individual telephone lines between conning stations, either ship may provide station-to- station phone lines for use between transfer stations. Talkers must ensure that telephone leads are ready to establish  communications  as  soon  as  jackboxes  are received aboard. To prevent injuries resulting from rapid surging of ships while they are alongside, talkers on the intership lines do not wear telephone neck straps; the telephone  lines  are  hand-tended. Careful attention should be given to the matter of jackbox  covers.  They  must  be  secured  tightly  by wrapping  the  phone  boxes  in  plastic  bags  when  the telephone  lines  are  being  passed  between  ships. Experience  shows  that  a  replenishment-at-sea  operation can be slowed by lack of attention to this small, but vital, detail. Hand paddle and light signals at replenishment stations parallel orders passed over the sound-powered telephones. During daylight, replenishment station Signalmen  render  hand  signals  with  12-  by  12-inch paddles; at night, red, green, and amber flashlights or colored  wands  are  used. At each replenishment station both ships indicate the  commodity  being  handled. LINE-THROWING GEAR Line-throwing guns or bolos are used to pass shot line between ships. Normally, this is done by the delivery ship except for carriers and other ships with aircraft  on  deck.  The  line-throwing  gun  fires  an illuminated projectile. The bolo, which is preferred for passing the shot line in daylight, consists of about 10 ounces of lead with rounded corners. It is well padded, encased in rubber or leather, and attached to the end of a nylon shot line. A 2-inch toggle is secured to the line about 5 feet from the weight. To use the bolo, you must grasp the toggle and whirl the weight about your head several times to gain momentum before letting go. Utmost  caution  should  be  exercised  when  a  line- throwing device is used because of the potential for possible injuries to personnel. A shot line is returned at the  earliest  possible  time  to  facilitate  preparation  of  the line  for  another  relay,  if  needed. Line-throwing  gunners  and  bolo  heavers  must  be well trained, and they must be outfitted in red helmets and red jerseys or red vests. Before firing or heaving the lines, the word is passed on both ships over the 1MC and/or by electric megaphone (bull horn) as follows: FIRING  SHIP:  “ON  THE  (name  of  receiving  ship), STAND  BY  FOR  SHOT  LINES.  ALL  HANDS TOPSIDE TAKE COVER.” RECEIVING SHIP: “ON THE (name of own ship), STAND  BY  FOR  SHOT  LINES  AT  (station(s) concerned). ALL HANDS TOPSIDE TAKE COVER.” Before firing the shot, each station on the delivering ship sounds one blast on a whistle. When ready to receive the shot line, each station on the receiving ship replies with two blasts. These two signals must be sounded each time the shot line is fired. The messenger is the main line used in hauling a rig between ships. If the delivering ship has difficulty getting its shot lines across, the receiving ship uses its own line- throwing  guns  when  requested  to  do  so  by  the delivering ship. The shot or bolo lines are used to haul over the messengers and then passed back at the earliest convenience  to  the  ship  furnishing  them. Replenishment stations are marked according to the commodity  delivered  or  received.  These  station markers are shown in figure 4-26. Figure 4-26.–Station markers. 4-31
