As fouls in sailboat racing penalize the offending boat but do not advantage the fouled boat, drawing a foul in fleet racing is almost always a net loss. However, when there are only two boats on the course any penalty for one boat is an advantage for the other. Therefore, in match racing a boat will often try to put itself in a position where the other boat will have no option but to foul it or make a disadvantageous change in course, even at the cost of sailing a slower course itself.
