Fuel consumption is the most decisive operational parameter deciding the profitability of a commercial fishing vessel. An all India survey conducted by ICAR-CIFT on the commercial fishing vessel designs reinforced the need for fuel saving. This work attempts to reduce resistance and optimize a hull form for a fuel efficient combination fishing vessel. The effect of optimization of hull form of a deep sea fishing vessel to reduce resistance is discussed in this paper. Computational Fluid Dynamics is utilized to simulate the vessel and arrive at the resistance at various operating speeds scientifically. Model testing to verify this resistance values and also to assess the maneuvering behaviour of deep sea hull form is described. It is very important to select an
appropriate main engine and reduction gear box to arrive at fuel efficiency. The introduction of bulbous bow in the forward hull bottom reduces wave resistance. A kort nozzle around the propeller increases the thrust during fishing. A deep sea fishing vessel hull was developed and constructed and trials were carried out to prove the fuel efficiency by various steps.
