Let me say about this 20 20 one then, I will, because, we will have more time for that, for
the same thing, for 20 20 maneuver. It says, first overshoot should be less than equal to
25 degree, something like that, see again, I will, just because we do not have so much
time, I will just try to tell you the logic behind this. What they are trying to say is that, 10
10 maneuver which is more logical, normally, you do not maneuver with a very high
rudder angle for 10 10 maneuver. The 1st overshoot and 2nd overshoot angle are
specified, your ship must maintain that criteria. So, first overshoot must be something
and that criterion is related to length and velocity. You can always workout, you now y l
by v etcetera, it is between 10 to 20 degree and in between, it is a it is a this formula is
absolutely a straight line interpolation between the two, if it is less than 10, so much
more than 30, so much and between 10 to 30, it is just linear interpolation this.
