ANALYSIS OF PROPULSION EFFICIENCY ON FISHING BOAT 30 GRT

摘要

Fishing vessel is defined as a ship, boat or other floating component used to do fishing activities, to support fishingrnoperations, fish cultivation, fish processing, fisheries training and research/exploration of fishery. The fishing boatrnconsist of ship or a small boat be in the form of canoe boat (without engine) driven by paddle power or sail, outboardrnmotor boats up to large fishing boat made of wood, fiber or steel with diesel engine propulsion. Shipbuilding materialrntake effect on the dimensions and shape of the hull. As the fiber ship using a chine hull while wooden boat using a roundrnhull, This will affect the ship resistance to the propulsion system. This study aimed to know differences of propulsionrnefficiency in the fishing vessels 30 GT with wood materials and fiber. The method used is the experimental method andrnthe Holtrop method. The results showed that the propulsion efficiency of the fiber materials and wood materials arernrespectively 0.55 and 0.53. This shows that the efficiency of ship propulsion with fiber material greater than 3.63% shiprnwith wood materials.
