    hi lethal...

    get a 4 foot straight edge and lay under the ski,

    place the edge at the rear of the keel in the middle of the boat,

    now the 4 foot edge will run out the back of the ski and under and past the ride plate,

    i have a small trolly jack and a block of wood which i jack in the cantre of the edge VERY lightly to hold in place to give you a free hand to measure the "kick" up from the straight edge upto the ride plate at the rear,

    hope this helps you measure you plate angle

    if a pic help as it often does feel free to ask and i will snap a few this evening (uk time) for you

    Is yours measuring .976 in photo?
    When comparing your numbers with others wouldn't it be effected the legnth of your plate, say old school riva versus R&D vesus protek versus shredmaster if measuing off the end?
    I haven't ever measured mine yet, but that pic helps a lot ! thanks

    That particular measurement started with the Riva R/d old style LENGTH plate. Anything else will only be in reference to it... like you said, the length and stuff will have an effect on your measurement. Even worse, if measuring something like a shred, it has a downwards sloping "keel"(don't know what else to call it) built into the plate.

    i sort of figured that that was how and what was measured but i wasnt 100%..thanks for the clearing up of that.. what is a general setting to go for (if any) and what does up or down result in..less speed more speed..bouncy???
    Thanks alot

    Top question..and when you lay the straight edge at the keel will it hit the part just behind the intake grate??? so should it rest on 2 places or just in the front. If just the front then mine is way off if that is the case PICS would be GREAT

    The straight edge should only touch the hull it should not hit anything else.

    Level should touch flat part behind center keel and pump shoe. Those are your 2 points of contacts. The hull is not flat and will not allow a true angle for measurement by itself. Many things affect rideplate measurements, Pump shoe placement, place of measurement, etc.. Every boat is different and should be taken that way.
