[1] Sometimes one point off the starboard or port bow is classified as fine to port/starboard, but this is not universal. [3] The point system is most commonly used on board merchant ships and recreational sailing vessels. Naval ...

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.
After over a quarter of an hour, a force from astern pushed the ship's bow up onto the floe, lifting the hull out of the pressure and with a list of five degrees to her port side. A gale overnight further disturbed the floe, driving it against the starboard side of the hull and forcing a sheet of ice upwards at a 45-degree angle until it ...
The port engine room contained the high pressure ahead (240 tons, 40 feet 2 inches (12.2 m) long with four stage expansion) and astern turbine (120 tons, 22 feet 11 inches (7.0 m) long) for the port shaft, the centre room contained two low pressure turbines with ahead and astern capability within single casings (54 feet 3 inches (16.5 m) long ...

Many modern ships have the following dial indications: Full ahead navigation (on notice to increase or reduce) Full ahead; Half ahead; Slow ahead; Dead slow ahead; Stop; Dead ...
The squat effect is the hydrodynamic phenomenon by which a vessel moving through shallow water creates an area of reduced pressure that causes the ship to increase its draft (alternatively decrease the underkeel clearance of the vessel in marine terms) and thereby be closer to the seabed than would otherwise be expected.
