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.

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.
The most forward and lowest curved part of the ship is the stem (not normally the extended part beyond the hull). The bow of the oil and chemical tanker Bro Elizabeth in dry dock in Brest, France. This ship does not have a stem. The stem is the most forward part of a boat or ship's bow [1] and is an extension of the keel itself. It is often ...
Diagram of the position of a centerboard on a boat Also centerplate (American spelling), centreplate (British spelling). A wooden board or metal plate which can be pivoted through a fore-and-aft slot along the centerline in the hull of a sailing vessel, functioning as a retractable keel to help the boat resist leeway by moving its center of ...
The Ulstein X-Bow (or just X-BOW) is an inverted ship's bow designed by Ulstein Group to improve handling in rough seas, and to lower fuel consumption by causing less hydrodynamic drag. [1] It is shaped somewhat like a submarine's bow. [2] Bourbon Orca anchor tug, shown in 2012, was the first ship built with an Ulstein X-Bow in 2006.
Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail-powered land vehicle.
