<![CDATA[The reliable of the engine room design can affect the success of the ship both in terms of the propulsion nor the self-righting. The design of engine room is one aspect of being able to apply self-righting capabilities. There is an innovation for the development of closed fast boats with self-righting capabilities which have not yet been found in Indonesia. Self-righting is the ability of the ship to be able to return to its original position after experiencing a rolling of 180 °. The design of engine room using the inherent self-righting method is one method to be able to apply self-righting capabilities. The focus of this research is to study the effect of the gravity point on the engine room longitudinally, vertically and transverse on the ability of self-righting. In the engine room obtained LCG 4,044 m, TCG 0.006 m and VCG 0.830 m. The self-righting simulation is divided based on 5 load case conditions. The condition of load case 1 the value is max GZ 0.732 at 51.8 °. The condition of load case 2 the value is max GZ 0.672 at 70 °. The condition of load case 3 the value is max GZ 0.577 at 61.8 °. The condition of load case 4 the value is max GZ 0.687 at 69.1 °. The condition of load case 5 the value is max GZ 0.596 at 59.1 °. At the 5 load case conditions has comply the HSC 2000 code stability criteria and can apply self-righting ability because it comply the requirements of having a positive GZ value of 180 °.]]>
