Last weekend I was kayking by the shores of Helsinki and happended to spot a kayak polo tournament by the local kayak club of Merimelojat (Seakayakers). Watching the game outside the pitch from my kayak was fun. Though I did not learn all the detailed rules of the game, I noticed that they have two referees and they give penalties. Later I learned that “A player in possession of the ball can be hand tackled by being pushed over on the shoulder or back”.
Kayak polo game seemed to be a very fast team sport where you need to know how to do eskimo rolls, throw and catch the ball and paddle well.
