The selection of main and auxiliary engines is a substantial design phase for powering ships. Considering the economic concerns and environmental measures, high-efficient, low-emission and suitable engines should be selected, installed and operated on onboard ships. In this study, the main and auxiliary engines of active 20 Bodrum Gulets are analysed and the hull forms of these yachts are modelled for resistance and power calculations. Holtrop-Mennen method is used for obtaining the total resistance of the selected yachts, and the design power requirements are compared with those of the actual data for environmental impact evaluation. Finally, the solutions to increase the energy efficiency of yachts are offered from the design perspective. According to the results, it is revealed that most of the yachts have larger engines causing higher fuel consumption and pollutant emissions compared to the design data. Considering the efficient engine operating conditions, the load factors of main engines operated in some yachts are very low or very high causing up to 6% higher fuel consumption compared to the data supplied by the engine manufacturers.
