I placed this under the category "Movies and Film" b/c I heard this
phrase while watching "Pirates of the Caribbean, Dead Man's Chest"
yesterday, and I heard one of the captains scream out "Port to
Starboard". I also heard this phrase in other movies (I believe this
phrase was also used in one of the Star Trek Movies). Anyways, I was
wondering what that phrase "port to starboard" means. Is it a military
phrase? B/C I usually hear this phrase in action and battle scenes in
movies.

P.S.: I don't think I've heard it being said the other way around
("Starboard to port") :-) .

Dear dho1115,

"Port to starboard" is simply indicating "left to right" in naval
terms. The port side of a vessel is her left side (relative to the
ship's bow, when facing forward), while the starboard side is her
right side.

"Port to starboard" can have various meanings, depending on the
situation. It can, for example, mean that something is coming close
the ship from the left side so that its direction points to the right:
An approaching torpedo's course could be reported as "port to
starboard". It could also define the course of another ship crossing
before the bow.

It's just the way seamen say "left to right" - and since Starfleet in
Star Trek has adopted naval customs, it is not too surprising to find
this expression also in space, where no man has gone before.

Hope this answers your question!
