    Hi can anybody help me with this one?

    I am working on a 2,4mR design.On these boats the keel is a substantial part of the displacement so it is crucial to get the position right.

    When I add the keel to the hull the displacement goes all wrong. It becomes less.

    What am I doing wrong. I add the keel and position it and cut out the part of the hull that is inside the keel. The keel goes some mm inside of the hull and it is not joined to make a polysurface, is that necessary?

    Check the direction outwards of the keel surface. Better to make one polysurface of the half boat.
