    HI all,

    I am working on a project and am required to extract the GZ curve of a model replica of an existing fishing boat

    The real boat weighs 2600kg, displaces 2.54m^3 water, length 6.7m (salt water - 1025kg/m3)

    The replica is 1:14 scale - measuring 0.479m. (fresh water - 1000kg/m3)

    How should I calculate the displacement of the replica? [If you had to divide the mass by 14, it results in 185kg! ... not very realistic I suppose!] Do I need to divide something qubed (^3)?


    thanks for your feedback!

    do you have lines or a point cloud for this boat. GZ will be a function of volume, as you need the center of bouyance
