How a kettuvallam is built

Jackwood planks, coir rope and no nails: a visit to the yard that repairs our boats.

A kettuvallam, the boat our houseboats are built on, was once a rice barge that carried paddy and coconuts across Vembanad to the markets. The word means a boat tied with knots, and that is how the old ones were made: planks of anjili, wild jackwood, stitched together with coir rope and sealed with a paste of cashew-nut shell oil and fish oil. No nails were used.

Our boats are repaired at a yard on the Pallathuruthy side, where Kunjumon and his sons have worked for more than thirty years. A new hull takes about four months. The planks are steamed and bent over a fire, then fitted one by one, and the coir stitching is pulled tight by two men at once.

Today the hulls of houseboats are still built in wood, but most have steel frames inside for strength, and the roof of bamboo and woven palm is laid over a wooden frame. Bedrooms, bathrooms and the kitchen are fitted after the hull is in the water.

Every boat comes out of the water every two years for the hull to be checked, re-oiled and re-sealed. That takes three weeks, and it is why some boats are not available in July and August, when we do most of this work.
