course
				   		Olympic events take place on a triangular course whose length varies depending on variables such as the characteristics of the water and the wind direction.
				
 
					
					
					
						tacking 
						Technique of navigating in a zigzag course when sailing upwind; the sails cross from one side of the boat to the other.
				  	
 
					
						second leg at reach 
						The sailboat first navigates the beam reach with the wind on the starboard side until the third buoy (first leg at reach), then sails a second straight line to the beam reach with the wind on the port side.
				  	
 
					
						lowering the spinnaker 
						The crew lowers the spinnaker when the sailboat turns into the wind, after the second leg at reach.
				  	
 
					
						starting line 
						Line marking the beginning of the race; when the starting signal is given, all the sailboats must be behind this line.
				  	
 
					
						buoy 
						Floating object that marks out the race. An Olympic-type race has three buoys that are arranged in a triangle; they are rounded in a specific order.
				  	
 
					
						start into a headwind 
						The race begins facing upwind; sailboats must then tack until the second buoy, which is located straight ahead.
				  	
 
					
						finish line 
						Line marking the end of the race; events are usually made up of several sets, the combined result of which determines the winner.
				  	
 
					
						wind 
						Displacement of air caused by variations in pressure between two regions of the atmosphere.
						
				  	 
					
						raising the spinnaker 
						When the sailboat navigates points of sailing (with the wind almost from behind), the crew increases speed by hoisting a large lightweight sail called a spinnaker over the bow.
				  	
 
					
						jibe 
						Technique for changing the sailboat’s course when the wind is coming from the rear by letting the sails cross from one side of the boat to the other.
