As they go around the mark they cannot touch it, and then they go on to the second leg. On the second leg the boats are going downwind, so they hoist their downwind sails(spinnaker) and go for what is called a gate in sailing, once again trying to get to the gate the fastest by gibing away from the other boat for clear wind or gibing toward another boat to take the opponents wind without getting penalized. A gate in is when there are two marks (buoys) and it is the crew’s choice as to which one they will go around once they start the rounding by going between the two marks and finish the rounding with only one mark next to them.
