This makes Team Racing a very tactical branch of sailboat racing - i.e. consider the following situation for 3-boat teams (the most common format): If one boat is in 1st place yet his team mates are in 5th & 6th then his team's entire points, upon finishing will be 1+5+6 = 12points, however the opposition will have 2+3+4 = 10points. Therefore to win the race, the boat in 1st will have to try and maneuver his vessel in such a way as to hinder the other teams progress enough to let his team mates overtake them. He can do this by using the Racing Rules of Sailing to his advantage - ie positioning himself in such a way that the opposition has to get out of his way, or they are the keep clear boat.
