For size perspective... I'm 5'6" and just under 200lb., and per DM it sounds like I woulda been considered huge by period sailor standards, to the point that when I was thinking about designing a home office after a frigate captain's cabin he made a good case to look at a three-decker's flag bridge instead.

Landlubber contrast, a US Army horse cavalryman even at the end of the pony soldiers could be no taller than I am but weigh no more than 120lb.
