noun - Dive turn is a rarely used move when an athlete is squeezed out of position coming into a turn buoy. Instead of stopping or crawling over other competitors, the athletes purposefully dives underneath the water's surface and under the other competitors. While underwater, the swimmers moves around the turn buoy rope and pops up on the other side of the turn buoy. The dive turn allows the swimmer to legally swim around the buoys in crowded conditions where they may be forced off-course or forced to stop or commit a rule infraction.
