    Eliminating porpoising????

    I am running the stock grate on my ski (see sig), but when running on glass I'm getting a fair amount of porpoising, despite VTS position.

    Anyone know if a new grate (R&D aquavein) will fix it? Or could it be the rear tabs (they're set to 'factory' position).

    Seams like the right thread to ask the question.
    I have GTR I am looking to stop or reduce porpoising. Like everyone else I don't want to lose speed. Will sponsons help? I know people out there have tried them on the GTR. Can anybody tell me if they help? I know Riva and Worx both make a set for the GTR. I think a grate would drop speed so I don't think I want to do that. Also what about ride plate mod? I hear jim's definitely increases speed but porpoises a little more than stock. Has anybody had Erik at Speedfreeks mod one for GTR? If so how is it on porpoising?

    sorry for my bad english porpoising is pitching the bow?

    if yes i think that you have to move your body on the ski.....you create the ski trim with your weight

    In a nut shell, the ski rocks from front to back so the bow isn't static at speed.

    Ride plate, trim labs & sponsons can help with this but some of the time its down to the sea condictions and hull design.
