    You get only 8.5 kts with 450 HP and 12-13 tonnes total weight? There is something wrong with either those numbers or your boat...
    Can you give some pics of your boat, pontoon hull in particular?

    With a full load, what is the immersion (depth) of the pontoons, relative to their diameter? What is the diameter of the pontoons? Length of the pontoons?
