The first overshoot Um. It should not be exceeded; further the second overshoot should
not exceed the first overshoot. Yeah see suppose first overshoot should not exceed, now
by the say here the answer is say say the l by v is so and so, that the answer is 12 degree.
Suppose the l by v are a ship is such that the first overshoot should not exceed 12 degree
then, 2nd overshoot should not exceed 27 degree, no 27 degree, 2nd overshoot will always
find as large and then actually all these ships, you know, you will find that it goes like
then, like that, I mean the this larger here, then stabilizes. It starts quickly, Yeah and now
just to quick, we say because, we have to very soon end the same zigzag maneuver.
Another criteria is there for 20 20 maneuver where, the stipulation is only for 1st
overshoot. 1st overshoot should not exceed 25 degree. Essentially, I want to tell you is
that, this is limiting, the zigzag maneuvers ability for the ship to turn, so, it should turn.
But here, they are concern about it should not turn, I mean that, the overshoot angles
have to be less, which means whether the ship turns or not, it should be safe. See, here
the I M O’s requirement is not that it, you know, supposing my ship turns very slowly
like that, it is a agreed to this thing, it is agreeable to I M O. So, I M O is not bothered if
your ship is really sluggish and turns very slow. They only want to make sure it does not
turn so fast. Your enthusiasm you have not given such a big rudder that it it well, turning
it, heels the bank on the side, that is what they are interested and the last one is the
stopping ability. I do not have so much time, but just to tell, there is a stipulation that the
ship should stop with in 15 ship length, that is all.
