One of the jobs that tabs do is help hold the bow down, If you use then to stop the chine walking you will loose speed. The reason most boats chine walk is that the drive is too high, center of thrust. What I mean is the engine and boat are faster than set-up. So I recomend a shorter foot, lower unit or short shaft. I have heard that the drive set-back can help this problem too. Does this boat have a delta-pad???
