This article didn’t feature although I think it is an interesting hypothesis:-
While ‘chewing the fat’ in the cockpit on passage this summer, we were all agreed that the forecabin was colder than anywhere else in the yacht. The most plausible explanation drew on some schoolboy physics. It was suggested that the bow being continually swept by water and drying in the wind, the ‘latent heat of evaporation’ was drawn from the deck and topsides thus cooling the forecabin. Another reason why this is the least popular cabin on passage!
