There is a question regarding the explosion in the main engine and 2 persons injured. And in answers, I am reading that master needs to inform and take permission from the owner and charterer as well. Whether it is to seek medical advice or in case of diversion. Why does master need to ask charterer if he is asking the owner about the course of action?
In heavy traffic situation which of these functions - Relative/True motion in conjunction with Relative/True vectors shall be used to get proper situational awareness? Also when and how the parallel indexing need to be used into the radar for strict control of the ship's movement?
