Flare is the angle at which a ship's hull plate or planking departs from the vertical in an outward direction with increasing height. A flared hull typically has a deck area larger than its cross-sectional area at the waterline. Most vessels have some degree of flare above the waterline, which is especially true for sea-going ships.
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 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.
The bow was given a significant flare, to offer protection against weather in the Pacific. The Fubuki -class vessels were originally intended to have only hull numbers. This proved to be extremely unpopular with the crews and was a constant source of confusion in communications with the earlier Kamikaze and Mutsuki classes , and naval policy ...
Garboard strakes and related near-keel members Diagram of typical modern metal-hulled ship’s exterior plating, with a single strake highlighted in red. On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear).
Tumblehome is a term describing a hull which grows narrower above the waterline than its beam. The opposite of tumblehome is flare . A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves .

The word "keel" comes from Old English cēol, Old Norse kjóll, = "ship" or "keel".It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work De Excidio et Conquestu Britanniae, under the spelling cyulae (he was referring to the three ships that the Saxons first arrived in).
