Flank speed. Flank speed is an American nautical term referring to a ship 's true maximum speed but it is not equivalent to the term full speed ahead. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft. Flank speed is very demanding of fuel and often ...
The engineers hear the bell and move their handle to the same position to signal their acknowledgment of the order, and adjust the engine speed accordingly. Such an order is called a "bell"; for example, the order for a ship's maximum speed, flank speed, is called a "flank bell".

Planing (boat) A Contender dinghy planing on a broad reach. Note the typical way the bow lifts up while the stern skims over the water. Planing ( / ˈpleɪnɪŋ / PLAY-ning) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift ( buoyancy ).
Bow wave of the USS Connecticut, on her speed trials in 1906 or 1907. The size of the bow wave is a function of the speed of the ship, its draft, surface waves, water depth, and the shape of the bow. A ship with a large draft and a blunt bow will produce a large wave, and ships that plane over the
The Spearhead-class expeditionary fast transport ( EPF) is a United States Navy –led shipbuilding program to provide a high-speed, shallow draft vessel intended for rapid intra-theater transport of medium-sized cargo payloads. The EPFs can reach speeds of 35–45 knots (65–83 km/h; 40–52 mph), and allow the rapid transit and deployment of ...
The Enterprise Air Group was established on 1 July 1938, encompassing all squadrons embarked in USS Enterprise (CV-6). The group was divided into four squadrons, each with eighteen aircraft dedicated to a particular role. The squadrons were designated according to their role, and all were given the unit number six, derived from the hull number ...
Background. As a ship moves in the water, it creates standing waves that oppose its movement.This effect increases dramatically in full-formed hulls at a Froude number of about 0.35 (which corresponds to a speed/length ratio (see below for definition) of slightly less than 1.20 knot·ft −½) because of the rapid increase of resistance from the transverse wave train.
