Use swimming techniques and cooperate in a team to score points by throwing a ball over a traffic cone. 

At the bow of the boat there is a tall traffic cone. There are 2 teams, swimming around the boat. The members of each team pass a ball 4 times and then throw it over the traffic cone. Then the other team takes the ball and does the same.

Instead of a traffic cone, each team has one member standing on the boat who has to catch the ball.
