Thanks for the information about St. Roch. It must have been a great experience to move aboard this schooner. However, However, I can also understand the claustrophobic attacks, it must be pretty cramped in there.
I have already had claustrophobic feelings seeing the film "Das Boot", which takes place in 1941 and shows the experiences of a German submarine crew during the battle of the Atlantic. It's completely unimaginable for me how one can stand it there for a longer time.
