The bow (/ b aʊ /) is the forward part of the hull of a ship or boat, [1] the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. [2] Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline.
Belowdecks: inside or into a ship, or down to a lower deck. [12] Bilge: the underwater part of a ship between the flat of the bottom and the vertical topsides [13] Bottom: the lowest part of the ship's hull. Bow: front of a ship (opposite of "stern") [1] Centerline or centreline: an imaginary, central line drawn from the bow to the stern. [1]
Schematic view of a ship's navigation lights indicating its port (red) and starboard (green) sides. 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).
A sharp bow on a conventional hull form would produce waves and low drag like a bulbous bow, but waves coming from the side would strike it harder. The blunt bulbous bow also produces higher pressure in a large region in front, making the bow wave start earlier. [6] The addition of a bulb to a ship's hull increases its overall wetted area.
A pitch motion is an up-or-down movement of the bow and stern of the ship. The longitudinal/X axis, or roll axis, is an imaginary line running horizontally through the length of the ship, through its centre of mass, and parallel to the waterline. A roll motion is a side-to-side or port-starboard tilting motion of the superstructure around this ...
Schematic view of the bow of a ship, showing: A the martingale stay, B the dolphin striker and C the bobstay. Bows of HMS Victory: three parallel bobstays, separate dolphin-striker with martingale stays. A bobstay is a part of the rigging of a sailing boat or ship.
