Bowloader
Encyclopedia
A bowloader is a crew shell (a type of boat
used in rowing
) in which the coxswain
lies semi-supine
in the bow, as opposed to the normal seated position at the stern
.
Bowloaders are often seen as coxed four
s and also coxed pair
s. Although a small number of bowloader eights
exist, the larger boat's momentum means that a coxswain lying in the bows could be injured in a collision if the bow collapses. A bowloader is slightly faster than a stern-coxed boat, since the mass of the coxswain in the bow reduces porpoising, and the semi-supine position puts the coxswain's center of mass below the waterline, reducing roll. Both of these factors help to reduce drag. The cox also has better forward vision in a bowloader: in the conventional stern position the cox cannot see directly ahead.
Novice coxswains often have difficulty with bowloaders, however, since the rowers and their oars cannot easily be seen. Experienced coxswains learn how to feel the movements of the rowers in the boat, as well as visualising the position of the shell itself to safely and effectively manoevre it.
Bowloaders require an amplifier
and loudspeakers to be used so that the cox can communicate with the crew, and unlike in the conventional coxing position there is no opportunity for personal communication between cox and stroke on race tactics.
Boat
A boat is a watercraft of any size designed to float or plane, to provide passage across water. Usually this water will be inland or in protected coastal areas. However, boats such as the whaleboat were designed to be operated from a ship in an offshore environment. In naval terms, a boat is a...

Rowing is a sport in which athletes race against each other on rivers, on lakes or on the ocean, depending upon the type of race and the discipline. The boats are propelled by the reaction forces on the oar blades as they are pushed against the water...

Coxswain
The coxswain is the person in charge of a boat, particularly its navigation and steering. The etymology of the word gives us a literal meaning of "boat servant" since it comes from cox, a coxboat or other small vessel kept aboard a ship, and swain, which can be rendered as boy, in authority. ...

Supine position
The supine position is a position of the body: lying down with the face up, as opposed to the prone position, which is face down, sometimes with the hands behind the head or neck. When used in surgical procedures, it allows access to the peritoneal, thoracic and pericardial regions; as well as the...

Stern
The stern is the rear or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship. Originally, the term only referred to the aft port section...

Bowloaders require an amplifier
Amplifier
Generally, an amplifier or simply amp, is a device for increasing the power of a signal.In popular use, the term usually describes an electronic amplifier, in which the input "signal" is usually a voltage or a current. In audio applications, amplifiers drive the loudspeakers used in PA systems to...
