This study aims to analyse the effect of variations in the addition of bilge keel on the value of resistance, ship stability, and seakeeping performances. The research method is carried out by designing and analysing the hull design of the fast patrol boat type with variations in the addition of a bilge keel. Variations made on the bilge keel include length and width. The length variations are considered by applying 4 m, 5 m, and 6 m, while the variations in width include 0.3 m, 0.4 m, and 0.5 m. This study indicates that the nine variations of the bilge keels model with a combination of length and width do not show a significant difference in the resistance value on each ship. Then, for the stability criteria, the bilge keel model IX, with a length of 6 m and a width of 0.5 m, has the best stability value compared to other variations. Meanwhile, the addition of bilge keel in the seakeeping simulation did not show a significant difference. The parameters of this analysis consider the primary needs of fast patrol boats to support the development of shipping technology.
