Most races that are held in the spring and summer feature side by side racing, or sprint racing, sometimes called a regatta; all the boats start at the same time from a stationary position and the winner is the boat that crosses the finish line first. The number of boats in a race typically varies between two which is sometimes referred to as a dual race to six, but any number of boats can start together if the course is wide enough.
