Fast Moving Punter
Typically, a punter pulls the punt pole out of the water until less than 1-foot (0.30 m) of pole is beneath the water. Then the pole is allowed to fall under gravity straight down through the punter's hands until it reaches the bottom of the river; pushing at this stage is counterproductive.
A punt is a flat-bottomed boat which does not have a keel, and is propelled by means of a long pole. Punts were introduced as pleasure craft in Edwardian times, since then punting has become one of the most popular ways to see the famous bridges and colleges along the River Cam.
