    Default Yet another bottom thread

    Here are a few pics of the project I am currently working on. I would like to talk about keel design. I don't expect for you guys to give it all up as you have worked hard for your knowledge and some do it as a job. I plan on doing this with myself, with help from friends also. Any advise you can give that would keep me from making stupid mistakes would be really appreciated.
    Some questions I have are as follows
    1 Do the relief pockets need to be the full length of the keel?
    2 Does the keel need to be Straight as viewed from the front. Look at mine and you will see it is straight and then bows out before the intake entry
    3 Do the chines of the tunnels need to be sharp or rounded or?
    4 How far forward does the bottom work need to Start.
    5 If the bottom of the sponsons are wavy is that hurting me?
    Sorry for the long post. email at [email protected] or pm if you don't want to post. Any help will be greatly appreciated. Thanks Scott

    OK I'll bite....


    Looks to me that the strakes were knife edged or damn close to it. Normally from what I have seen/read bottom work is only done to the wetted area of the boat, this would be about four feet from the transom. I have seen guys also run the bottom work about three/ four feet from the intake as well. I personally would leave the relief pockets alone and the length of the keel. Yes the keel needs to be straight, the reason yours flattens out is for water entry I'm guessing. Your sponsons are normally only in the water at low speed and at speed they should just "dance" over the water, so they probably are not hurting you. IF the boat were mine I would clean them up just because I am OCD that way. Hope this helps

    For starters, the Intake absolutely needs to be installed in the boat! the hull will fit to the intake and will most likely create hook when you bolt the intake to the hull in some areas! (Could get wavy next to the intake fins)
    I saw your thread earlier, but was in full A.D.D. at that time and didnt notice what you were asking.
    I will give you my thoughts on the bottom, but not on here!...opinions are like shitheadz, and............................awe, nevermind!

    Super Jet, I was thinking the strake or chine on the tunnel would need to be thin and crisp. Less wetted surface at the rear.

    Todd, the boat is not ready for the intake yet. But the bottom already had some pretty gnarly hook in it. One quarter inch on the left side of intake. I posted these pics to get some ideas thrown around about relief depth, width, symmetry etc.. I wonder why the relief pockets go from wide to narrow and wide again? Completely different than a eliminator etc.. Thanks Scott

    With all do respect......you will generally end up re-doing the areas that you may have already done with the hook, once you fasten the intake to the hull, Its most likely gonna change!

    Are you planning on flipping the boat back over to install the intake?......then re-flipping the boat over to address the keel/sponsons (Blueprint the bottom) again after the intake is in???? (Just doesn't make much sense bud!)
    Hope not to offend you, but it seems that you have jumped the gun!...or have I misread anything?
    Thanks

    Sorry Todd, I think I mislead you. The boat was flipped to address some delam in the front of th sponsons, fix the bow eye and strip the rest of the paint. It is easier to flip it and work standing than work upside down and around the trailer. Once all of the repairs are made and paint stripped, I will flip it back over finish the glass work inside the boat and set the intake. Sorry for the confusion bud! Just trying to get some ideas kicked around with the pics posted. Scott

    scott what kinda intake you goin back with? lowpro? im thinking bout trying to find a miersch intake for my lil tunnel and jus putting it in place of the old regardless if it moves the pump forward alil, my pump is so far setback i think it could stand jus a replacement then tiny loading keel blended to that.

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