In stock game ,after I ordered "back emergency", a boat at 9 Knots will decelerate to 0 Knot in less than 20 seconds.But in this mod，it takes several minutes.

yes, sir, i am having the same experience.
boat driving/handling is a combination of many factors.
the guys behind FOTRSU have configured those factors in such a way that it is difficult to drive the boat like an automobile....which is true in real life. watercraft do not have the same physics as autos on pavement.
so....you need to train your crew on how to handle your boat on the surface as well as submerged.
when i get a new boat i use the time on the way to my first objective to figure out how she accelerates and how far (long) she takes to come to a stop.
it's part of the game, man.
have fun!
