Feasibility of Electric Fishing Boats based on Evaluation of Hydrostatic Forces and Resistance

Abstract

Conventional gasoline engine fishing boats have several disadvantages, such as high exhaust emissions, high fuel consumption, and low service life. The disadvantages of the gasoline engine can be resolved by using the electrical engine. Electrical fishing boats is an improvement on conventional boat to reduce the fuel consumption and emissions. In realizing an electric fishing boat, a feasibility analysis of the design, shape and weight that can be accommodated is required. The feasibility of an electric fishing boat has been successfully carried out by simulating the boat on Maxsurf Software. The aim of this research is to analyze feasibility of conventional boats by designing electric fishing boats. Improving feasibility is carried out by calculating hydrostatic forces and resistance. Electric fishing boats design using the simulation model in Maxsurf Modeller and simulation of resistance in Maxsurf Resistance at speeds of 1, 3 and 5 knots, with Wyman method. The modeling results show that the electric fishing boat design has a pointed front configuration with a V-shaped bottom. Main dimensions LoA 3.49 m, width 0.8 m; height 0.5 m; and a draft of 0.2 m, the boat produces a hydrostatic force which includes a displacement of 301.5 kg, a midship draft and submerged area of 0.2 m, a wet area of 3.08 m2, and a waterline of 0.5 – 1.5 m. Testing 1, 3, and 5 knots, the boat experienced resistance of 26.11 N, 234.96 N, and 652.73 N respectively. The power required for the boat to operate was 13,43 W, 362.66 W, and 1678,97 W. The feasibility of designing an electric fishing boat is the main key to developing an electric fishing boat.
