    Default flat keeled 19ft tunnel rideplate demensions?

    my nordic seems to bounce the nose alil more than i'd like over 80 and i'm thinking the rideplate is alil too wide and too short. it sticks out past the hull only 6inches, but its 10inches wide just doesn't seem right to me, but i also don't get these flat keeled tunnels is the keel so flat that's all the rideplate it needs? or can i build a longer , narrower rideplate?

    as soon as the bow starts packing some air under it, i can feel the boat rock back and forth alil, almost would call it porpuse'n i'm thinking it needs more plate to lean the boat back on, but this is my 1st 19ft tunnel and i'm not sure if its that, or the downfall of the keel

    Dare to be different, if it turns out great you can claim you planned it that way.

    On another thread, this was also talked about and it was said to see how true to the hull bottom it is... Meaning put a straght edge on the boat bottom and then adjust the ride plate(s) so they are even with the bottom. I couldn't answer your question but remember reading about this just this morning.

    i'm gonna try less angle and build a plate 3inches longer, see if that helps.i was at 4* and i think it may have been too much, the boat had 2* when i got it.

    Make it zero and see what that does before making anything. I forget who said it, but the plates can act as giant hook in the bottom.

    hook is a downward facing curve, not a up curve i'll try 2 and see if that gets rid of it.

    It's funny how it's just you and I talking about this and those who might be able to help are staying away from the subject.

    yeah id make it about 4-6 inches longer, with side plates so no bending and run her at 1-2 up...should work wonders for it flat keel sucks tho. Friend had same boat and we got it to run pretty good. If i remember the plate stopped a bit past the turn pins on berkly droop snoot maybe 1" or so ??


    Oh BTW when u get her up and runnin its gunna unhook like a bitch.....flat keel...use pressure guage and adjust shoe depth

    its the flat keel that scares em i know its shit, but i do have to say , i can leave flatter and quicker than most 19ft tunnel cause the keel is flat, sob planes out soooooo damn fast, but i can tell it hurts the boat above 80.

    is his pump set back? my pump is as far forward in a tunnel hull as they could put it my bowl bolts are prob 3inches from the transom, just nuff room to get them out with a wrench.

    ya....transom split handhole cover so its a 1/2 setback..lol...had a blown 454 it her..i guess for lack of a better term you have to "force" water to the pump by lowering shoe and that of course will cause really bad things to happen if motor quits at 95...ur going swimmin' 4 sure
    capps did a keel on another friends 19 flat keel daytona...ran great after it was done if boat is perfect and u r keeping it id do that well worth the coin IMHO

    i'll see ervin friday nite or saturday, he'll be up at the ftcobb races, gonna have him take a look under it. boat has too many stress cracks for me to consider having keel work done, its just not that nice a hull.if i can keep the pump loaded and run 85, shit i'm happy 85 on a pump gas 10.5 to 1 468 is gooooooood and it's getting there!

    Thats fast enough for you anyway

    make ride plate longer and dont go so high up on your plate in degrees and try that. It all starts off of the keel line, shoe then ride plate.
