The starting whistle echoed over the pool. Water began to fly from boat to boat. The action was all part of an intramural Battleship game, where 75 people gathered to play a real-life equivalent of the board game as a fundraiser for the American Heart Association.

Teams boarded aluminum canoes and were tasked with sinking their opponent’s “battleship” by flinging water scooped from the pool in plastic buckets. Players had to weigh the balance between trying to sink other boats and making sure their own wasn’t filling with too much water.

The event raised $400 through player donations and sponsorships, which will be combined with proceeds from a 5K race to make a donation to the American Heart Association.
