noun - Buoy is a distinctively shaped, colored or marked float, sometimes carrying a signal, signals or logos, anchored to mark a race course, channel, anchorage or swimming hazard. It can be referred to as a turn buoy or intermediate buoy or guide buoy in a triathlon or open water swimming competition.
Turn buoys are directional in nature and must be passed on a specific side of the body as race instructions dictate. Intermediate buoys or guide buoys are directional in nature, but can be passed on either side as the swimmers choose.
The swimmers had to go around four buoys in the 10-kilometer course.
