Have you ever gone cruising in a houseboat on the backwaters of Kerala? If you haven't, make sure you do. This one is really a wonderful and unforgettable experience!
Present day houseboats are huge, slow moving exotic barges used for leisure trips, and are in fact reworked version of kettuvallams of olden times. The original kettuvallams were used to carry tons of rice and spices. A standard kettuvallam can hold up to 30 tons from Kuttanad to the Kochi port.
The kettuvallam is held together with coir knots. Not even a single nail is used during the construction of the boat.. The boat is made of planks of jack-wood joined together with coir. This is then coated with a caustic black resin made from boiled cashew kernels. With careful maintenance, a kettuvallam can last for generations.
