Kerala Champions Boat League.

The Champions Boat League (CBL) has been conceived by tourism officials in Kerala on the model of the Indian Premier League (IPL) to transform the state’s legendary and historically-significant ‘vallamkali’ (snake boat races) into a world-class sporting event.
Snake boat races owe their origins as far back as the 13th century when princely kingdoms, located in present-day Alappuzha along the backwaters, would have raging battles in the water.
