    Octura dual rudder alignment

    Hi Everyone, I have a Octura twin rudder setup on my 30 inch mono and the boat likes to run off to the right. When i add more left steering on the radio to counter act the boat runs slower due to drag. The rudders are towing in.
    My question is, What position do the rudders need to be in?
    Straight, towing in or towing out? I am using an Octura x440 3 blade balanced prop.
    Any Ideas,
    Chris.

    Both rudders should be true to forward motion. Parallel to travel. Anything else will create more drag. Some things you should check or fix that can cause a slight right turn are dull prop edges (they should be very sharp). Driveline might need to be offset to counteract prop torque. Hull bottom might be warped or not trued.

      Dual rudders are a drag.

          Setting dual rudders are a pain. Make sure both are exactly parallel to each other. They need to be identical. If it has a tie bar make sure it has no flex. I run my BBY OM29 with the rudders 0*. I use a angle finder and measure the trailing edge and also the bottoms so they are the same hight.
          If all of your wishes are granted, many of your dreams will be destroyed!
