Speed boats are used as sea transportation for sailing activities, tourism, and other maritime transport. One aspect that affects the performance speedboat is the design of the hull structure. This research to investigate the influence of various rise of floor variations on the resistance of speed boat. The stages involved include literature review, model creation using Maxsurf Modeller software, inputting data, and running simulations using Maxsurf Resistance with Savitsky pre-planing, Savitsky planing, and Holtrop calculation methods. The results of this study indicate that the best angle efficiency is achieved with the Savitsky planing method, with the lowest resistance25 degree angle of 25.7 kN and power 277.507 kW, while the highest resistance and power are observed with the Holtrop method, with maximum resistance at 21-degree rise of floor angle of 51.3 kN and power of 554.278 kW. These results suggest that higher rise of floor angles tend to improve energy efficiency.
