The continuing rise in the cost of fuel oils has highlighted the need to place more emphasis on improving the fuel economy of fishing vessels. Factors which influence fuel consumption of fishing vessels are (a) hull design (b) the resistance of appendages, such as keel, cooling and other protuberances on the outside of the hull, (c) fouling of the hull (d) machinery (e) the propeller design and (f) the fishing gear and methods of fishing. Fishing is hard hit by the rise in fuel prices. This is especially true of trawlers. Because of high fuel consumption of trawlers, there has been considerable development in the use of large diameter propellers and nozzles and large reduction gears to improve efficiency. In a fishing vessel eg: trawler, between 80% and 90% of the total energy input is in the form of fuel for the propulsion machinery.
