Among all them, the most renowned one is the Nehru Trophy Boat Race. It was started in 1952 on the occasion of the visit of India's first Prime Minister, Jawaharlal Nehru to Alappuzha. Now, it is a major event held on the second Saturday of every August. It features the gigantic snake boats of Kerala, the Chundans, which were once the battleships of the Malayalee King of Yore.
At present, the boat race has grown as the most important tourist event. The boats are sponsored by different villages of Kerala for this boat race.
