Lotka building is a prevalent profession among the inhabitants of the Caspian Sea and is inherited from father to son. The Lotka builder first designs the bottom of the boat, after preparing the necessary timbers. Then he cuts the corners of the timbers and attaches them using nails.
This is a very sensitive task. Because timbers must be properly paired together to prevent water penetration. Thereafter the boat’s skeleton is formed by timbers. Then the inner frame of the boat is carefully cut and placed in equal parts of the boat’s length. Cutting and placing pieces of wood is very important in this profession. While constructing a boat, Lotka builder must weigh the balance on Lotka’s corners carefully and cut additional parts of the boat.
After sanding the boat is ready to be wrecked. It usually takes three days to build the boat.
The size of the Lotka depends on the river it is thrown into. For example, the Lotkahas that are built around the village of Sarakhshki and the outskirts of the Lotka eco-tourism settlement are smaller than the Lotakahs that are thrown into the Sefidrud Delta on the outskirts of Bandar Kia Shahr because of the narrow rivers around them.
