Canoe Battleship - Don't sink the ship
The jet of water hits you square in the chest, blinding you for a second. Your teammates yelling, "keep going! they're almost sunk!" Wiping away the water, you fill your bucket and heave the water into the enemy boat, and down she goes, to the depths of the pool. Winner!
