@donaldsc - The thing is that there are people who prefer and appreciate the comfort inside the ship as well. After all, people will spend more time on the ship than outside the ship. The expeditions last for only a few hours. The entire journey during the drake passage is in the ship, which can be 3-4 days in total.
Point is, there is a reason why Ponant, Swan Hellenic, Silversea, Seabourn, Viking, etc. exist, because there are people who would like to be comfortable when they are in the middle of nowhere.
