The AIS and radar are alarmed and the duplicate chartplotter in the salon is always on so one can walk down and check if the alarm goes off.
So its only acceptable to look at the chart plotter in the cabin only. Then I suppose if you have not heard the alarm and you are on station 24/7 he must alert you, which is in the standing orders and I assume he is not allowed to return to the cockpit for at least 30 minutes as you do not like personnel / crew to be there because as you say they would have impaired vision from looking at the chart plotter. Your DOC ref. You then would take all the necessary action required that set the alarm going in the first place. Obviously in a major shipping lane only and possibly not when in the wide open high seas cruising in calm waters and 14 knots or so wind.
