Design and Development of Electric Long-tail Boat Propulsion System for Tourism Promotion at Klong Bangmod, Thung Khru District, Bangkok

This project aims to change the propulsion system of a longtail boat from an internal combustion engine to an electric motor. It includes designing and calculating the size of the motor and accessories such as the propeller size, electric battery, conveyor drive system, and appropriate anchor points. The motor and accessories will be installed in the real boat hull, and a long-tailed boat will be tested at Khlong Bangmod to analyze the results and the functioning of the system.The hull consists of two main parts:A long-tailed boat with a size of 5 meters, capable of supporting the weight of 3 passengers.The transmission system, which acts as a power transmission mechanism. The original power source, an internal combustion engine, will be replaced with a hub motor-type electric motor. A system will be designed to transmit power from the motor using a large pulley attached to the motor. Power will be transmitted through a belt to a small pulley below, continuing to the shaft and then through the long tail shaft of the original long-tail boat. The performance of the internal combustion engine long-tail boat propulsion system will be tested and compared with the electric motor propulsion system in terms of distance, time, speed, acceleration rate, fuel consumption, power consumption, noise level, etc. This data will be used to calculate the rate of energy consumption and measure the noise level in order to compare engine boats with electric boats. The economic worth of changing from an internal combustion engine to an electric motor propulsion system for the longtail boat will also be studied.The benefit of this project is that it can serve as a model for electric long-tail boats for the community and villagers, helping them understand the value of using electric long-tail boats and promoting the use of alternative energy sources. It can also serve as a guideline for further development in the business of converting existing boats into electric ones, as well as contribute to public relations and tourism promotion in the Bangmod Canal area.The expected outcome of this project is that longtail boats converted to electric propulsion will be more economical compared to internal combustion engine boats. They will have greater long-term value, allowing users to save on travel expenses. Additionally, the conversion will result in reduced noise levels, addressing noise pollution issues in the communities along the canal. Other types of pollution such as air pollution from engine smoke and water pollution from engine emissions will be eliminated, reducing the heat released into the canal. As a result, the Bangmod Canal will have a better and more pleasant atmosphere, while helping the community members reduce their fuel costs.
