When measuring, disregard the strakes and follow the Vee of the hull. Trim tabs should follow the Vee at the junction of the transom and the bottom of the boat. In the case of inboards , the complete run from chine to keel may be utilized if it is an unbroken span of the same angle. Protrusions such as strakes may be bridged provided there is no change in angle on both sides. Many factors determine the appropriate size and type trim tabs for faster boats.
Special consideration is required when selecting trim tabs for performance applications.
