This is like the board Game ‘Battle ships’ where you have to try and sink all the opposing team’s boats. First, you need a divider of sorts, about the height or a volleyball net or higher, so that each side cannot see the other (eg. a rope tied at each side of the hall and a large sheet draped over it or big boards put up in between).
Next, have each side find a spot where they are not allowed to move from. When the game starts, each side is given a ball and then proceeds to try and hit the other team with the ‘bomb shells'(balls).
If someone is hit with the ball, catch it or moves from their spot, then they sit to the side until the game is over.
Note: each side needs people (runners) to fetch the ball once it has bounced and give it back to the Ships.
God bless and good sailing.
