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 ship. [21] Yardarm: an end of a yard spar below a sail.
The speed of sailboats through the water is limited by the resistance that results from hull drag in the water. Ice boats typically have the least resistance to forward motion of any sailing craft; [2] consequently, a sailboat experiences a wider range of apparent wind angles than does an ice boat, whose speed is typically great enough to have ...
A cardinal mark is a sea mark (a buoy or other floating or fixed structure) commonly used in maritime pilotage to indicate the position of a hazard and the direction of safe water. Cardinal marks indicate the direction of safety as a cardinal ( compass ) direction ( north , east , south or west ) relative to the mark.
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.
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.
The method for tacking of sailing craft differs, depending on whether they are fore-and aft, square-rigged, a windsurfer, a kitesurfer, or a proa.. Fore-and-aft rig – A fore-and-aft rig permits the wind to flow past the sail, as the craft head through the eye of the wind.
Cardinal day beacons are used to indicate the position of a hazard and the direction of safe water as a cardinal direction (north, east, south or west) relative to the mark. This makes them meaningful regardless of the direction or position of the approaching vessel, in contrast to the lateral mark system.
The ship is in the 130-degree position, with its bow on the left and the starboard deck edge just rising from the water. Parbuckle salvage, or parbuckling, is the righting of a sunken vessel using rotational leverage. A common operation with smaller watercraft, parbuckling is also employed to right large vessels.
