    I am trying to predict the resistance of a fast transom stern vessel using Lahtiharju method. I have read the Lahtiharju (1991) paper, however I am still a bit confused how to apply the derived equations to predict the resistance of my vessel. Also, why doesn't the method work at low speeds/Fn when used in resistance prediction software.

    Any clarification or link to better explanation would be great.
