Abstract

Fishing vessels are generally used for finding, fishing, and containing fish during their operations. To meet the industrial demands in fishing, one of the potential research is performance analysis for a variety of hull types of fishing vessels. The conventional design. This research is conducted considering the monohull type as the main subject. Hull analysis on the fishing vessel is focused on the resistance criteria with expectation the results can be used as a reliable reference for the fishing vessel industry to increase the effectiveness of the hull design, which furthermore gives positive benefit for the fishermen and the industries. The resistance criteria are estimated using two well-known approaches, i.e., Savitsky's mathematical model and Holtrop's regression-based method. Comparative study of the hull design is extended to discussion of methodology effectiveness in resistance analysis. Research results concluded that in the comparison of three variations of the hull, the type of monohull with dagger board fin has the smallest total resistance value compared to other introduced hull models. The total resistance value of the monohull with a dagger board fin of 30° using the Savitsky model is 34 kN while the Holtrop method provides 35 kN. Compared to the numerical calculation, both methods show gaps below 15% which makes the methods well enough to be used for resistance estimation, especially for the fishing vessel.
