Origin of Nehru Trophy Boat Race :The Nehru Trophy Boat Race was originated in 1952, on the occasion of the visit of the then Prime Minister of India, Pandit. Jawaharlal Nehru to Alapuzha. In the race witnessed by Nehru, 'Nadubhagom Chundan' stood first. In the excitement of seeing the performance by the oarsmen, Jawaharlal Nehru jumped into the Nadubhagam Chundan, forgetting all security arrangements.
The Prime Minister donated a silver trophy, which is a replica of a snake boat placed on a wooden abacus. The trophy bears his signature and the inscription "To the winners of the boat race, which is a unique feature of community life in Travancore - Cochin." The trophy is known as 'Nehru Trophy' later and is awarded to the winners of this boat race every year.
Legend of Boat Races : The story of the boat races (Vallamkali) in Kerala goes back to 400 years in the history of Kerala. The Rajas of the erstwhile kingdoms of Chempakasseri (Ambalappuzha), Kayamkulam ,Thekkumkoor (Changanacherry) and Vadakkumkoor (Kottayam) in the old Travancore area, frequently had wars between them. All these places now comes under Alapuzha district of Kerala.
The Chempakasseri Raja and his troops suffered severe casualities in the war they fought in the backwaters of Kuttanad. The Raja found out that the defeat was because of the defects in his war boats. The Raja summoned all the boat architects of his land and asked them to build new faster boats. The reputed architect of Chempakasseri, Koduppunna Venkitanarayanan Asari, built a new faster boat which had all the requirements the Raja specified. The boat had speed and it had the capacity to carry 100 warriors on board. In all the subsequent wars, the Chempakasseri Raja emerged victorious.
The Kayamkulam Raja who suffered defeat from the Chempakasseri Raja, appointed a spy to study the building of the boat from Koduppunna Venkitanarayanan Asari. The young, handsome youth seduced the architect's daughter and promised to marry her. The man was taught the construction of the boat by the Asari. The spy disappeared from the place,once he thought, he learned the secret behind the boats. He constructed the boats for Kayamkulam Raja, but the new boats proved no good, in the next war. The snake boat design is very difficult to learn. Even today, it requires many years of training under a master boat architect, before one could undertake a boat construction.
