BS, meaning language that doesn’t map to reality, on a vessel is a luxury in a way. It comes at the expense of the safety margin. Vessel with large margins can afford it at the cost of higher risk.
When I worked in Alaska on the small vessels, tugs and the small freighter we could not afford to depart far from the reality of our situation. Any errors we made were soon made apparent from feedback from the sea, weather or the navigation situation.
In the military with large crews BS is kept under control by replacing it with chickenshit, like keeping your shoes polished.
With large commercial deep-sea vessels the amount of BS depends upon the command. In many cases it can be quite high in my experence.
