An outrigger stabilizer is a developed product attached to a floating structure by means of increasing the stability of the floating structure. The presence of outrigger has a definite effect on the heave, pitch, and roll motion of the craft as compared to the hull without an outrigger. Stabilization is used to counteract the forces of a boat's rolling motion. During fishing activities such as netting, casting or fishing if the wind or waves are strong at the coastal area, it will increase the probabilities of rolling motions on the boat. While using the outrigger, the extra stability comes at the cost of increased weight complication in the setup and the drags are increased with the installation of device. The aims of this study are to design the adjustable double-outrigger stabilizer for the small fishing boat and to determine the stability of the outrigger. The AutoCAD software is used to design a mould of the double-outrigger and the Maxsurf software is used to analyze the stability with the outrigger. As a result, the adjustable double-outrigger stabilizer for the small fishing boat is produced with adjustable arms providing the boat with necessary buoyancy and stability.
