Abstract:	Speed boat is a fast boat category that has high service speed, this is marked by Froude Number (Fn) which is greater than 1.2. In operating the speed boat has a very critical problem regarding the trim, where the empty ship conditions often experience stern trim so that the captain cannot look forward, for that innovation the addition of the stern fin is applied to the speed boat. This study aims to obtain parameters and trim angles close to the keel event by varying the angle of the stern fin and area and location vertically using laboratory tests in the Engineering Faculty towing tank laboratory. Trim conditions are obtained using a sports camera after which trim measurements are carried out using the Auto CAD program. This study found that the appropriate Fin size was 0.36 m2 and the fin stern trim location suitable for the speed boat was on the side of the stern with the position of point 0 of the bottom transom in the direction of the transom, with the ideal angle used was 60 against the flat plane according with transom position.
