What customs and courtesies should be observed on an US Navy ship Quarterdeck?




I found this description of "Quarterdeck Manners":

"A Navy Ships Quarterdeck is considered a ceremonial area and should be treated as such. No skylarking or loitering is allowed. The Officer of the Deck has complete responsibility and authority on the Quarterdeck and should never be challenged.

On approach from the ships brow to the quarterdeck one must turn and face the flag (aft) or salute the flag if military and covered. One must then turn and show ID and salute the Officer Of the Deck and ask their permission to come aboard (enlisted) or state that they have permission to come aboard (officers). When leaving the ship it is done in the reverse order and one asks permission to go ashore (enlisted) or states that they have permission to go ashore (officer). Hats or headgear are not allowed on the quarterdeck unless they are part of the wearers uniform. The Quarterdeck should not be used as a passage from one part of the ship to another. If it is necessary to do so permission from the Officer of the Deck must be requested and granted".

In other words, the "manners" or behaviour expected on the quarterdeck is very ritualistic, formal and hierarchical, so the "manners" or atmosphere in the Banyan CLub will be the opposite, i.e. informal, so staning on ceremony, no hierarchy etc.
