Maluku waters are dominated by extreme weather conditions with wave heights of 1-5 meters.Purse seine fishing vessel is one type of fishing vessel that has very poor transverse stability.One way to improve the stability of the ship is to change the shape of the monohull ship to a ship with a trimaran hull type.This research was focused on examining the movement characteristics of purse seine fishing vessels with trimaran hull type kaiser copy stands with Axe-Bow modification on the bow and without Axe-bow, through computational fluid dynamics.The use of Axe-bow on trimaran is able to significantly reduce RMS Pitch, product which is an average of 13.
35% smaller when compared to Trimaran without Axe-bow.On the RMS Heave Trimaran Axe-bow can reduce an average of 5.27% if the Trimaran is without Axe-bow.Furthermore, the Trimaran Axe-bow is also able to reduce the RMS Roll by an average of 3.98% compared to the Trimaran without Axe-bow.
The results of this study can provide an initial description of the advantages of using the Axe-Bow on the Purse seine fishing trimaran ship.
