The video provides a step-by-step overview of how a fishing boat is built, a process that typically takes around three months. The construction process includes:
Building the Base: The foundation of the boat, known as the ‘aerav’ or keel, is laid on a 12mm thick plate. The keel for the boat in the video is 95 feet long.
Assembling the Frame: The frame or ‘mattam’ is constructed by hand-bending angle irons and welding them to the keel.
Adding the Sheets: Metal sheets are added to cover the frame. The sheets for the bottom of the boat are 8mm thick, while the upper sheets are 6mm thick. A chain block is used to lift the heavy sheets into place.
Installing Tanks and Components: Inside the completed hull, diesel and water tanks are installed, with iron strips welded inside to prevent liquid from sloshing. The boat’s engine, propeller, and rudder are also installed with a crane.
Finishing Touches: The boat is painted with an anti-fouling paint on the bottom to prevent marine growth. Plywood is used for the deck and wheelhouse, which is built piece by piece on the boat.
Launching: After about three and a half months, the finished boat, named ‘Marva,’ is launched into the water using a rail system. The video notes that the final cost of a boat like this can be around 1.75 crore rupees due to the high price of iron.
