procedures

In the event of high seas and/or severe weather, would passengers have been prevented from using the passenger promenades or weather decks? The reason I ask is that it seems unlikely that an emergency boat would be launched in those conditions for a man overboard.

Were there sea/weather conditions in which passengers would be forbidden access to the promenades and weather decks? The reason I ask is that under severe conditions I would assume that an emergency boat wouldn’t be launched for a man overboard.

Does anyone know what procedures were followed to have the emergency boats and its davits manned at a moment’s notice? Were specific crew designated and standing by at a particular location? How long would this watch last?
