Rules for Swimming Etiquette If you are the only swimmer in a lane, you can swim by following the center line. If there are only two swimmers in the lane, it can be divided into halves, with each swimmer swimming on his or her own side of the lane. Alternatively, the swimmers might adopt the "circle" format indicated below. If the lane has more than two swimmers, or if you enter the water beyond the end of the lane, you should stay to one side of the pool so as not to interfere with other people's efforts. The most common mistake new swimmers make is going straight for the deep end. Unless you are a strong swimmer, it is best to start out toward the shallow end and work your way gradually deeper until you learn how much force your body can generate in the water. It is also important to realize that others may be trying to avoid hitting you. They will usually do this by staying away from any spot where you may be likely to go under the surface. So if you see someone else in the pool, try to let him or her know that you are approaching by waving your hand or shouting "hello." Finally, remember that others may be watching you to see how they should position themselves in the pool. If you normally dive in the deep end, then others will probably do the same thing. If you normally swim close to the wall, others will probably follow your lead.
