Port and starboard are nautical terms for watercraft and spacecraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other.
Port: the left side of the ship, when facing forward (opposite of "starboard"). [1] Starboard: the right side of the ship, when facing forward (opposite of "port"). [1] Stern: the rear of a ship (opposite of "bow"). [1] Topside: the top portion of the outer surface of a ship on each side above the waterline. [1] Underdeck: a lower deck of a ...
Bow, stern, port, starboard, fore and aft are nautical terms that convey an impersonal relative direction in the context of the moving frame of persons aboard a ship. The need for impersonal terms is most clearly seen in a rowing shell where the majority of the crew face aft ("backwards"), hence the oars to their right are actually on the port ...
Tacking or coming about is a sailing maneuver by which a sailing craft (sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction.

Often the cardinal mark system is used instead when confusion about the direction would be common. A vessel heading in the direction of buoyage (e.g. into a harbour) and wishing to keep in the main channel should: keep port marks to its port (left) side, and; keep starboard marks to its starboard (right) side.
The linear transverse (side-to-side or port-starboard) motion. This motion is generated directly either by the water and wind motion, particularly lateral wave motion, exerting forces against the hull or by the ship's own propulsion; or indirectly by the inertia of the ship while turning.
1. A position half way along the length of a ship or boat. [13] 2. A position half way between the port and starboard sides of a ship or boat, as in "helm amidships", when the rudder is in line with the keel. [13] ammunition ship A naval auxiliary ship specifically configured to carry ammunition, usually for combatant ships and aircraft.
This contrasts with the rest of the world, where the standard is the opposite, i.e. green markers must lie to starboard and red ones to port. red-to-red A passage of two vessels moving in the opposite direction on their port sides, so called because the red navigation light on one of the vessels faces the red light on the other vessel. reduced cat
