Do you answer navigational questions underway as well?

Yes, as one skipper standing by another. You have somebody at the other end who knows the situation you are describing and who thinks it through with you, like an experienced colleague in the next cockpit. That is expressly part of passage support, not only the mental side.

What that does not shift: final responsibility for the navigation and the vessel rests always, under all circumstances and at all times, with the skipper in charge on board. We do not give instructions and cannot give them, because we cannot see what you see. In the end you decide.
