N2  - Due to mandatory requirements Energy Efficiency Design Index (EEDI) and Energy Efficiency Existing Ship Index (EEXI)) prescribed by International Maritime Organisation (IMO) for new and existing ships, there is an increasing concern about the reducing the carbon emissions from the ships to have a sustainable environment. Several energy-saving technologies are adopted to reduce fuel consumption and increase the efficiency of the ships. Since past two decades, high-speed crafts are fitted with different types of appendages for drag reduction such as stern flaps, stern wedges, trim tabs, and hull vanes. Amongst all the appendages, the hull vane is found to be one of the suitable appendages at various Froude numbers (Fn 0.2 ? 0.7). hull vane is a fixed foil which is attached at the stern part of the vessel to improve the local pressure by altering the stern flow. This paper investigates the effect of the hull vane which is retrofitted to a high-speed Displacement vessel in 1:35 scale with different locations and angle of attack. A numerical study was carried out using Reynolds Averaged Navier Stokes equation (RANS) based Computational Fluid Dynamics (CFD) on Froude number ranges between 0.2 ? 0.45. It has been found sinkage and trim has reduced significantly up to 20 percent along with the drag of the vessel. To validate the present numerical study, towing tank experiments were conducted and compared. It was found that the numerical results were in good agreement with the experiments. Future studies are planned to optimize the hull vane design and orientation for better efficacy
