Quant pole

A quant (quant pole) is a pole used to propel a barge (barge pole) or punt through water. A barge quant often has a cap at the top and a prong at the bottom to stop it from sinking into the mud. A quant used with a punt is about 2 metres long and made from either wood or a hollow metal, so that in either case it floats if left in the water.
A quant is used not only to propel such craft, but also to steer them by acting as a rudder. The operator of the quant can stick the quant behind the barge or punt to determine the direction of travel.
Using a quant
1. Propulsion
The operator stands at the back of the barge or punt. The angle at which the quant is held depends on the depth of the water and the desired speed of travel. A steeper angle is required for deeper water (the bottom of the quant must be able to reach the bed of the river or canal) and a shallower angle required for speed. The operator drives the quant downward and slightly backward to push the craft forwards. To reverse, the quant can be pushed forwards. The quant is then pulled out of the water by placing hand over hand on it and pulling upwards (as if one were climbing down a pole).
2. Steering
By dragging the quant at angle behind the barge or punt upon the water, the craft can be made to turn. The craft will slow on the side on which the quant is in the water, so the craft will move into that direction. The greater the angle made between the quant and the barge or punt, the greater the turning angle. This effect can be enhanced (greater turning force) by pushing the quant forward through the water on desired direction side of the craft.
