The Kevuvallam / Kettuvallom (houseboat in Kerala) was a large floating structure with high loading carrying capacity was a part of Kerala's culture and heritage over the past years. Kettuvallam (houseboat in Kerala) could sail harnessing wild energy. A journey through the lagoon is interesting, passing through sleepy villages, busy boat jetties and vibrant celebrations. The boat glides across the shimmering blue waters with gorgeous green and fringed edges. The small cargo boats called Kettuvalloms are frequently used in the waterways for the above purpose. " Kettu" literally means to tie up and "Vallom" means " boats". The boats played a major role in the economic development of ancient Kerala, moving cargo and men from the very nook and corner of otherwise unreachable area, cutting across the length and breadth of the land. Fifty years ago, there were more than 5000 kettuvallom in the backwaters of Kerala, mainly used for transporting goods.
