"Dujmaj nIHDaq tlhInganpu' tu'lu'!"
Translation:There are Klingons on the right side of our ship!
I think starboard bow specifically means the right front of the ship. The klingon sentence makes no mention of whether it is the right front, middle, or rear so it should just be starboard without bow added on. Disclaimer: I don't sail and was never in the Navy. Also was only a pirate in my dreams.
