Kerala Houseboats (Riceboats) or kettuvallam are country boats that were used in the early days for the transport of goods from the isolated interior villages of Kerala Backwater areas to the towns of Alleppey, Kollam, Cochin and Kottayam. With the advent of roads, bridges and ferry services, gradually the kettuvalloms went off the scene. Presently, these kettuvalloms are back again as a major tourist attraction as a modern moving boat house in the backwaters of kerala.
Kerala houseboat sizes vary from about 95 feet in length and a width of 13 feet width for one bedroom houseboat and larger houseboats having 107 feet length and 19 feet width. The materials that go into the making are all local and Eco friendly bamboo poles, coconut fiber ropes, bamboo mats and coir carpets. The main wood used is "Anjili".
