    It's my belief, and i'm by no means an expert, that running the boat flatter is not only safer, but quicker. During the course of the weeked that pic was taken i ran the nose at three different levels, none of which affected the ET much. I did the same with my v-bottom rogers. Flying the nose never really made my boat quicker. Getting the entire hull out of the water with adjustments to the underwater hardware did though. the fastest pass i made the weekend of that photo there was 8.83 seconds and it was with the boat running flatter than what you are seeing in the photo. yes i am working on a new motor. CS19 and the other guys that have been racing tunnels longer than i have could probably give you better info than i have. This is just my short experience with the two boats i've raced.

    I'm no expert, but I'm going to say that a boat running the nose higher in the air may not be having less water drag then a boat running there nose lower. Each boat is setup differently so your going to get differrent results. Intake position, shoe cut, ride plate position, motor position, bottom modifications, etc.... I think to answer the question there is just too many variables to really say one over the other.
    You can run the nose up really high on a tunnel and have less water contact to the hull, but you have to remember your also putting the back of the hull deeper in the water then if you were set up to run really flat.
    A good example of a quick and flat running setup is Roznos's 18' CP which is practically straight when he's running it down the track, and not to mention super quick.

    Looks like you're on one hellava pass.
    I'm working on improving the setup in R.R.
