Fuel efficiency is the goal of every ship, the accuracy of the motor selection, propulsion efficiency, as well as in the hull design for reducing drag. There have been many innovations in ship hull forms, such as the bulbous bow, transom steering, changing shape and becoming a multihull. This study adopted the NACA 4412 experimental as a Hull Vane® that other researcher carried out and perform with CFD simulations, then compared them with experimental results. The suitability of the trend can be further developed by varying the angle of attack from NACA and changing its position to the hull. The angle of attack variations on 1o, 2o, 3o, and positions change to the ship draft and AP-after perpendicular. Changes in the angle and position of NACA were investigated of their effect on the resistance component. From the analysis of the wave resistance, the most magnitude resistance decrease founded at the NACA position at a distance of 40 mm Trailing Edge of ship Draft and 85 mm Trailing Edge of AP. The lowest wave resistance was generating by the angle of attack of 3o, with a significant decrease of 19% compared to 1o. The more considerable lift drag was obtained after Fn 0.3 from NACA at an angle of 3o and the smallest at 2o. This investigative study was presented in graphs and data as well as conclusions and discussion of the results.
