Ooo...you got my attention at the age of sail.My area of expertise (if I can be said to have one) is a little later, the Victorian and Edwardian eras. I also know a fair bit about the Age of Sail. If you have any specific questions, perhaps you could run them by us. I'm sure one of us could help.
My setting is Regency inspired ‘tis all. It was a bit of long shot, and I tend to borrow from Edwardian and Victorian times anyhoo. Things like manners and ranking stayed fairly static over those times. Just putting my wee feelers out really.For what reason? And any particular time or place in those thirty years?
I know a little about Native American societies in North America at this time [but probably not as much as others around here].
