    I have been designing a inland ro ro barge of 17 m length
    I HAVE USED THE FOLLOWING FORMULAS FOR RUDDER DESIGN

    Rudder Area (A1) =5.5% of (L*T)
    Rudder area,A2=(K/100)*LBP*d
    Area of rudder=(A1+A2)/2
    T = 0.9b+0.5b+X
    X= 0.05D-.0055D
    c=A/b=

    As per the calculations the chord length of the rudder falls greater than the span.And it is around 1m which does not seem possible. I will be grateful for any help.

    faithfully,
    paul

    Should we re-design or just rebuild my rudder?
