3.  Never smoke or have coffee cups and soda cans or bottles on the quarterdeck. 4.  Never cross or walk on the quarterdeck except when necessary. 5.  Don’t  lounge  on  or  in  the  vicinity  of  the quarterdeck. 6.  When on the quarterdeck, salute whenever the quarterdeck  watch  salutes  (as  during  a  gun salute). Shore  stations,  as  well  as  ships,  have  areas designated as the quarterdeck. The same rules apply in all cases. A    messing  compartment    is  where  enlisted personnel eat; the  wardroom  is where officers eat. If you enter any of these areas while a meal is in progress, you must uncover. Officers’ country   is the part of the ship where officers have their staterooms and wardrooms;   CPO country   is where the chief petty officers have their living spaces and mess. You must avoid entering these areas  except  on  official  business.  Never  use  their passageways as thoroughfares or shortcuts. If you enter the wardroom or any compartment or office of an officer or a CPO, you must remove your hat, unless you are on watch and wearing the duty belt. Always knock before entering an officer’s or a chief petty officer’s room. IN A BOAT The  basic  rule  in  Navy  etiquette,  as  in  civilian etiquette, is to make way for a senior. Thus the rule for entering boats, airplanes, and vehicles is seniors in last and out first. (Enlisted personnel board a boat first, leaving room, of course, for officers.) The reason is that the captain should not have to wait in a boat for a less senior  person  to  amble  down  the  accommodation ladder. When the destination is reached, the senior is allowed to disembark first as a mark of respect from juniors. In general, seniors take the seats farthest aft. If officers are present, enlisted personnel should not sit in the stern seats unless invited to do so. Enlisted personnel maintain silence as long as officers are in the boat. (For reasons of safety, personnel should never become noisy or boisterous in a boat regardless of the hour, condition of the sea, or who is present.) The boat coxswain salutes all officers entering or leaving the boat. Enlisted personnel seated well forward do not rise when officers enter or leave the stern seats. Personnel in the after section, however, rise and salute when  an  officer  enters  or  leaves.  (Although  it  is customary  to  stand  when  saluting,  this  formality  is dispensed with if the safety of the boat crew would be endangered.) When boat awnings are spread, enlisted personnel remain seated at attention while saluting; they do not rise under these circumstances. A boat assumes rank according to the rank of the highest  grade  officer  embarked  in  the  boat.  The coxswain and senior officer in each boat salute, with the person  in  the  junior  boat  saluting  first.  Other  crew members stand at attention; passengers sit at attention. The rules of etiquette for personnel aboard airplanes and other vehicles are the same as for boats. Boats passing a ship during colors must lie to, or proceed at the slowest safe speed. The boat officer, or in his or her absence, the coxswain, stands (if safe to do so) and salutes. Other persons in the boat remain seated or standing, but do not salute. ADDRESSING AND INTRODUCING NAVAL PERSONNEL Custom,  tradition,  and  social  change  determine how  members  of  the  naval  service  are  introduced. Although tradition and military customs generally hold true,  there  are  some  differences  in  methods  of addressing  and  introducing  military  personnel, depending on whether you are in civilian or military circles. The proper forms of addressing and introducing naval personnel are summarized in table 9-1. Except as provided in the paragraphs that follow, all officers in the naval service are addressed or introduced with the titles of their grades preceding their surnames. Officers  of  the  Medical  or  Dental  Corps,  and officers of the Medical Service Corps having a doctoral degree, may be addressed as “doctor.” Likewise, an officer of the Chaplain Corps may be addressed as “chaplain.” However, if a doctor or chaplain prefers to 9-16 Student Notes:
