Leisure Boat Concept Design: Study on the Influence of Hull Form and Dimension to Increase Hydrodynamic Performance

Abstract

The tourism sector contributes significantly to the economic growth of the community and the country. Labuan Bajo has the potential for marine tourism, which is famous for foreign classes. The separation of the islands in Labuan Bajo requires transportation to support tourist activities to tourist destinations. One type of transportation to support the needs of marine tourism is leisure boats or recreational boats. The leisure ship must have standards of comfort, security for passenger safety, and efficient operational costs. It is necessary to have infrastructure in the form of a leisure ship that functions optimally, so research on the hull’s hydrodynamic characteristics is essential. This research aims to observe the influence of hull form variables and primary size on the hydrodynamic characteristics of the ship. The research method was the simulation method to determine the response of the hull model variation to the environmental conditions tested. Simulation testing using Maxsurf software based on resistance, stability, and seakeeping criteria. The MADM method analysis results showed that the Deep V Hull model variation had the highest score of 0.787. In the sensitivity analysis calculation, the hull form variable significantly affected resistance and stability testing with R square values of 0.6008 and 0.5930. Meanwhile, the size variable had more influence on seakeeping testing, especially roll motion, with an R square value of 0.4081.
