Rowing competitions are mostly held in natural waters such as rivers, lakes, etc. There may or may not be a coxswain on the boat. At the beginning of a rowing competition, the boats are lined up behind the starting line. After the starter gives the order, the boats row to the finish line at the fastest speed and the winner is determined by the first boat to arrive at the finish line.
