if the ship is moving forward
and you are looking over the STARBOARD side
the water will apppear to be moving from LEFT to RIGHT
if you are looking over the PORT (previously known as the LARBOARD) side
the water will appear to be moving from RIGHT to LEFT
if the water is not moving....the ship is stopped
p.s. the PORT side light is RED....think Port as in wine. And no, do NOT call them 'running lights'. There is no such thing as running lights in the nautical rules of the road. It is a term used by sand peeps. There are side lights, mast head lights, stern lights, anchor lights & special purpose lights ... but no running lights.

by tradition, compartment (room) numbers, as well as life boat numbers are even to port and odd to starboard. How to remember? Count the letters 4 } even } port; 9 } odd ... So on a double ended ferry, how do you tell the 'true' bow? Look at the numbers!
impress your friends with your salty talk....
