    Remember there are TWO parameters: Degree of list (rotation around the longitudinal axis) and draft of the hull (translation along the Z axis). You can have the same degree of list, but if the hull is not the same depth in the water you won't get the same wave. This translates to mass in the hull, which brings us back to my earlier comment: These big hulls require lots of ballast.

    I said the rub rail at the surf-side corner needs to be at the waterline. But in our case we also need some ballast in the offside to bring the overall hull deep enough in the water (sufficient hull draft) to get the required displacement. As I recall, the offside corner of our swim platform is a few inches below the water surface when sitting still, due to a few hundred pounds of ballast on that side.

    To me this sounds like it should be a good wave but just wasn't that good without more people. We tried some bow weight today and that just knocked down the wave so I think I need more rear weight before adding bow weight.
    Bingo - it's going to take more weight to get that 24 foot hull deep enough to work its magic. But once you DO get there... wahoo! Your "crew of about 8-10" gave you a taste of what's possible. 8-10 adults probably add 1500-2000 pounds of mass. If they're absent, you have to make that up with ballast.

    Thanks for the great info ID

  3. Old thread i know, Did anyone ever remove the chines? Wondering if that had an effect on the wave or not
