I recently got to see the Nina docked at the same pier on Lake Michigan as the Friends Good Will (1812 sloop). They're roughly the same size. The Lady Washington (Interceptor) is about 10' longer than FGW, just for reference.

And yeah, the idea of 100 sailors crossing the Atlantic in a ship that size gives me the cold grues. I think FGW's usual crew is 5-8, not counting paying customers who sometimes are drafted volunteer to help haul on lines and such.
