In Oxford and Cambridge there are many commercial organisations that make punts available for hire to the general public; it is a popular tourist activity. Some colleges hire their punts to the general public, most let only students use them. There are a few punts owned by private individuals registered on the Thames and River Cam.
Punting is a more popular tourist activity in Cambridge, because many very attractive old colleges are built adjacent to the river, whereas the rivers in Oxford are generally further from the old colleges and pass largely through parks and fields. However, the popularity of punting beside the old colleges in Cambridge produces significant congestion on this relatively narrow stretch of the river during the peak tourist season, leading to frequent collisions between inexperienced punters. These collisions are mostly harmless, but can occasionally cause the punter to lose balance and fall into the river, causing rather more amusement to bystanders than to the tourist who may not have a change of clothes. Some tourists may prefer the calmer experience that the rivers in Oxford (or the upper river in Cambridge) have to offer.
The rudder method of steering can be slow (as while you are using the pole as a rudder you're not using it to propel the punt forward). A faster method, requiring more skill, strength, and judgment, is to drop pole slightly away from the punt (turning right for right handers) or slightly under the punt (turning left for right handers) and push backwards as normal. The generated torque will rotate the punt, probably too much if you are not experienced.
One particularly challenging aspect of punting is steering the boat underneath a wide bridge. The punter must judge when to propel the boat last before going under the bridge; if he does it too late, the quant will not fit under the bridge and the punter will have to let go of it (or, if he does not, this would knock him into the river); if he does it too early, the boat will lose its momentum and come to a halt underneath the bridge, and the punter will be unable to continue punting (except, of course, by pushing off the bridge, which is however considered cheating by many).
Alternatively a student can be employed to do the punting.
