Anyone tried this
 

I was wondering about evading destroyers... Lets assume one has been spotted, you then launch a T3 fat 2(circular runner) before diving deep and going silent.Does anyone know the minimum straight line distace before turning,it's radius and how many turns it will do? I ask because on silent my movement foreward is dm slow and i am hoping that the law of averages wil be in my side once i'm in its turn.
Cheers

It's not so much a circle as a ladder run with 800m and 1600m ladder lengths and it runs at 30 kts.
