MODIFICATION OF 30 GT FISHING VESSELS USING HULL VANE NACA 2408 TYPE FOR REDUCING SHIP RESISTANCE

With the territory of Indonesia which is mostly waters, fishing vessels are an important transportation tool in Indonesia to support the economic needs of the community, especially in coastal areas. When a ship sails, ship resistance will occur, and to achieve high effectiveness, the goal of all ship design processes is to obtain as little obstacles as possible. Modifications to the ship by adding Hull Vane mounted under the hull of the ship is done so that at high speed, Hull Vane can produce lift that can reduce obstacles that occur on the ship. This study uses a computer program based on Computational Fluid Dynamic (CFD). Based on this study shows that fishing vessel with the addition of hullvane with a variation of NACA 2408 on 2 ° angle of attack with Fn 0.527 can reduce resistance about 51.53% from the ship without hullvane.
