RV Vaikundam has nine well-appointed cabins with attached washrooms on the lower deck and, a well-functional kitchen, air-conditioned and exquisitely set dining hall and bar with lounge on its upper deck.

Vaikundam is a boat whose hull was modelled on the traditional Kettuvallom or rice barges of the past. The rooms are made using wooden panels with wall papering, wood panelling, sparkling wooden flooring and the upper deck has some bamboo matting with bamboo poles for roof, following some of the traditional practices but contain all modern amenities.

The wooden hull of the boat on the upper segment is made by joining planks of local wood ‘Aanjili,’ using strong coir rope on the segments above the waterline. The wood is coated with a caustic black resin made by boiling cashew kernel and fish oil. The wood is periodically treated with the Neem oil and Fish oil. This is the traditional style called Kettuvallum.
