Ships do not "just sit there".. They travel on their programmed route at 5-7 knots. I noticed sometimes once they are hit their props stop immediately, then resume. I also noticed no measure of evasive maneuvers are taken by the other merchants or even the merchant that was hit, they just continue :/.
And I've yet to see a destroyer try and detect me once their escorted convoy is hit. They just trot along their merry way. We all know that's not realistic, the destroyer would break off and make an educated guess based off the direction the ship was hit, and start their observations...
