About Aditya

The State Water Transport Department of Kerala operates about 100 ferry boats of different sizes from 75 to 100 passengers all over the state. These boats all single-hull boats, either made of wood or steel and powered by a diesel engine. 

Around 2013, these boats became unsustainable due to the increasing operational costs. This is the problem where Navalt steps in with their alternative. The zero-emission and the pleasant ride are an added advantage of Aditya. 


Aditya redefines inland water transport across the country and it is already in operation for more than 4 years. Also, it is the winner of the Gustave Trouve Award for the World’s Best Electric Ferry in 2020. 

Usually, if we purchase a similar solar electric ferry from Europe, it may cost us around 7 crores INR. Astonishingly, Navalt is able to manufacture a similar solar electric ferry within half of the European price which is around 3-4 crores. 

Technical overview

Aditya has a catamaran hull with a decrease in drag up to 1/3rd when compared to a ferry with a similar size. The solar electric ferry requires two 20kW AC motors for going ahead. The solar panels on top of this ferry can recharge it for 6 hours of operation on a proper sunny day. The lithium cell battery pack can offer a range of 85km and the ferry can reach a top speed of 14kmph. It has a seating capacity of 75 passengers.
