Naming conventions

STARBOARD the right side of the ship, when facing forward
PORT the left side of the ship, when facing forward.
It should be noted that port and starboard are absolute. The starboard side is always the same side of the ship, even if you are looking from a different angle. Looking from the front, to the rear, the starboard side would be on your left!

AFT the rear of the vessel
QUARTER a rear side part of the ship, the rear left is the port quarter
SHOULDER a front side of the ship, the front right is the starboard shoulder
DORSAL the top surface of the ship
