Large jet aircraft have what is called a take and go around speed (TOGA), once this speed is achieved its understood that there is not enough remaining runway for the aircraft to stop and that the only option at that point is for the aircraft to go flying.
I mention this as it seems to me that the pilot of a large vessel should have some similar protocol for obstacle avoidance taking into account ship speed, trajectory, and stopping time..
In other words, at a certain speed/distance from an obstacle, the vessel should not be moving toward the obstacle.
I believe we used to call this common sense.
