    Classic 22 with Arneson

    Hello,
    Has anyone performed the Arneson swap on a Classic 22? If so what was the experience? What did you do about bow lift etc? How was the rough water handling?

    Thanks for any and all input!

    Best,
    Matt

    I won'r elaborate, but it's generally not the best or easiest solution to your performance wants and desires,
    besides the cost.
    Generally the bow won't lift and the boats will inevitably run flat.
    There's been a couple of exceptions.....one was an 18 and not a 22, the other is a 20' Minx, which has a porpoising problem.

    When I was setting up my 22 I was going to use an Arneson ,as I raced with Howard and was racing when he developed his first one . However everyone said the SCX would be a better fit and would give me more lift .

    How did that work out for you? ...Ed

    Buiz, you mean Kenny Lessard? He had one installed, but if my memory serves me, he could never get it to perform properly. He ended up selling the boat.

    I'm pretty sure it was never finished.

    to paraphrase Ken

    I took a 60 mph and made it a 45 mph boat


    I would think a BH hull over a reg 22 hull might respond better with the built in rocker but I bet you would nee Arny rocker plates as well

    Hope Jeff will chim in but since he added Arneson rocker tabs to his Minx & using a 4 blade Rolla 23 pith prop it's working much better. The pic here does not have the rocker tabs on the Minx yet.

    nice pic mighty mouse was entirely different after the arny rocker plates too. I guess the marine engineers on the board can discuss the difference the short strakes of the minx and the longer strakes of the 22 and how they will react to the arny surface drive

    The minx is just a 4 foot longer 16 ski sporter hull the minx has no built in intentional hook does it? from the pic I would say no looking a Jeff's boot stripe it almost looks like there is rocker in the hull

    Kenny couldn't get the bow lift but I had the opposite problem. Out of anything I tried, the 17.75x23 4 blade Rolla helped the most. The added length of the rocker plates cured the porpoise. I do not run them in rocker mode. Just a tick down. 280 K planes would have probably done the job as well. I have just acquired my own Rolla. Next year I will see how fast it will go. I like the setup and it really shines in rough water. I also have bow tank which helps quite a bit.
    The porpoise was so strong, 210 pounds of sand bags in the front wouldn't stop it. It blows my mind.
    All is well now. I moved the fuel tank back 19". I should have just left it.
    I will attempt to measure the long CG again. Nothing like a good project!

    Also, running these boats in flat water is absolutely boring.

    Whats the difference in a Black Hawk drive and a Areson drive. I found a Black Hawk and folks say they will swap ends...Will the rocker plates help. Maybe strakes on the bottom of the rocker plates that go into the water 4" to 6"...Not trying to high jack, just trying to learn.

    Blackhawk is a surface drive but counterrotating twin propellors. Arneson is a surface drive but a single prop. Blackhawks do not normally swap ends , they swap which surface of the boat is out of the water

    Strakes provide a 10x or similar downforce on the water ( psi ) as the water that originally rose up to hit them. Think hanging onto a fire hose. That force lifts the hull.

    You DO NOT want to lift the transom so I'd put that idea to bed.
