The Kettuvallam or 'boat with knots' is called so because coir ropes tied in knots hold the entire structure of the boat together. During the entire assembling work of the boat, not a single nail is used. The boat is made of huge planks of Jack wood (Artocarpus hirsuta) or 'Aanjili' and joined with coir.
