    Default Set back pump and 18' Rogers Bonneville

    Ok so its not a Rogers, but it is the same hull. It is a 18 Advantage, built from the same molds as the Bonneville.
    The boat had a bone stock berk intake set in the factory location, which is basicly set, from what I have heard it called, as a half setback, with hand hole half in and half out the transom.
    I have pulled the intake out. I have cut out My intake from the Kona, which is machined for shoe and rideplate and will be installing it in the boat.
    What I would like to hear is, experiances and opinions on a 18' Rogers Bonneville with a full setback pump, where the hand hole is entirely outside the transom. I know there have been some good setups on these hulls.
    Which pump location does the hull perform best with? Since the intake is out I an just trying to decide to go full setback or put it back half setback.

    I have another Advantage, same hull only as an openbow. It has a Berk E pump and HTP bolt on shoe and ride plate, which is basicly a full setback pump with hand hole outside, but the E-pump and the JG are two different animals, as far as the intakes are concerned. How ever with this set up and a diverter, the boat runs really well for what it is.

    I did a full setback on the Kona, and the two times that I was able take it out and make a pass, it seemed to perform really well, although I did not have any thing to compare it to.

    What year is your hull? My good friend has an 1987 18' Advantage and if memory serves me correctly, his hand hole is not exposed at all. He has all the usual suspects (droop, PD, built jet and ride plate) and he gets that boat up to mid 80's with about 500 hp.

    Mine is an '86, The handhole is half in half out and has the large or extended stock transom cover. The boat will have a 489 bbc, with close to 700 hp.

    Hey Hal, how's it going. I didn't think you would go very long without building another boat.
    I may know someone interested in the open bow Advantage.
    You should have come down for the last SCJB get together, a few of your Vegas brethren
    were out. It was a good time, see you at the next one.

    Default Set Back

    I have a 18' super cyclone which has a little different bottom, but I did a full set back and it works great. My boat weighs 720 lbs. empty which is not a verry light hull and I weigh 310lbs. With 690hp it runs 98mph and 10.35 in the quarter mile (at ming). My friend drove it, he weighs 220lbs and he went 99.9 on GPS.

    I don't think that you will be disapointed with a set back in that boat.

    bigdog, that boat is getin it!
    I know they are diffrent bottoms, but close to same hp. If mine were to run even close to that I would be stoked. Were You able to compare performance from original pump location vs. the setback?
    Looking at the bottom of my hull, it seems to be some what of a rockerd bottom. I also looked at the bottom of the openbow and same thing, bottom looks rockerd. Does any one know if the original 18 Rogers Bonneville had a rockerd bottom?

    I can't draw a pic but rocker is when the bottom bow's down like a rocking horse. Opposite of having a hook in the bottom were the bottom looks like it sunk into the bunks on the trailer. Hope this makes sense.

    thats pretty good description. im at least on the right track now. is that across the whole bottom like a hook, or just by the intake on a jet?
    ill start a new thread for my other question about "spoon"

    I was told it's called a break bottom. You don't want it to be straight the whole length of the keel.
    At a point the bottom changes its angle. This allows the boat to take a set and ride on the back of the hull.
    Less wetted surface and a better ride attitude.
