Indonesia, as a maritime country, has a vast territorial sea that requires efficient sea transportation. Fast boats are an important solution to support sea transportation mobility, patrols, and logistics activities. Fast boat design needs to consider hull shape and the selection of appropriate materials to produce optimal, stable, and efficient structural performance. This study was conducted to analyze the effect of hull geometry and material type variations on the structural strength of fast boats through 3D modeling based on Finite Element Analysis (FEA) in design software. Three hull shapes were analyzed, namely V-shaped hulls, round hulls, and flat hulls. The three shapes were then adjusted to three material options, namely aluminum alloy, AISI 1036 steel, and titanium. Each model was given an external load of 1,000 N as a simulation of the force acting on the structure, so that the stress values, deformation levels, and strains that appeared in each combination of shape and material could be obtained. Based on the simulation results, it was found that the V-shaped hull using aluminum material showed the best performance, with the smallest deformation value and a relatively higher strength-to-weight ratio compared to other combinations. Aluminum was chosen as the best material because it has a lower density, good corrosion resistance in marine environments, and provides higher energy efficiency compared to steel and titanium. In conclusion, the V-shaped hull design and aluminum material can be recommended as a superior fast boat design concept in terms of structural strength, operational stability, and motion efficiency when operating in water.
