Preliminary design of 5 GT fishing boat with electric motor propulsion for daily coast fisherman

Indonesia is an archipelagic country with a large number of daily coastal fishermen. The majority of fishing boats use diesel as fuel, on the other hand, solar energy as a renewable energy source is widely available in countries that cross the equator. This paper aims to conduct a preliminary design of a 5 GT fishing boat’s use of solar panels as electric motor propulsion for daily coast fishermen. Based on field data processing, it was found that the appropriate fishing boat size was 10 m in length, 2.2 m in width, 1.1 m in height, and 0.55 m in the draft. The results of the design show that the electric motor propulsion fishing boat can operate optimally using solar energy is 7 hours with a sailing distance of 9 sea miles. These results can be used as a reference for the substitution of fossil fuels into renewable energy so that they can provide the benefits of low daily operating costs for daily coast fishermen.
