Tim Bolt didn’t really like sport at all until he discovered something both new and unusual. “I was listening to the radio one day when I heard something that I thought must have been a joke. The DJ was talking about underwater hockey! When I realized it actually was a sport, I decided to find out more about it. To my surprise, I found a local team and before I knew it, I was part of it!”

Unlike water polo, where the action takes place above the water, underwater hockey is played at the bottom of the pool. Players wear masks, flippers and snorkels during the game. “The rulers are simple, you just have to slide the puck into the opposing team’s goal,” says Tim.

Underwater hockey was invented by a British diving club in 1954. Tim told us, “Unfortunately it’s not much of a spectator sport, as all people watching from outside the pool can see are lots of splashing and flippers!”
