“People were much smaller in those days”
The myth
The human race has, over time, gotten a lot taller. You just have to look at the deck beams on historic ships, with a height of around 4-5ft, to see that people in the past were much smaller than they are today, practically hobbits!
The reality
This one has some truth, as levels of nutrition in diet can cause variations in height. However, it’s never been to extremes where the entire population is less than 5ft tall.
The average height on the Mary Rose is 5’7, which is the same height as Star Wars actor Mark Hamill. Now, he might have been a little short for a Stormtrooper, but you wouldn’t mistake him for a hobbit. (Although Martin Freeman, who played Bilbo Baggins in the Hobbit movies, is also 5’7, but that’s just confusing the issue!) You can find out more in our other blog on the subject.
So, why are the beams so low? Essentially, it’s due to the material properties of wood. On historic ships you generally have a lot of weight on each deck, be it supplies or heavy bronze and iron guns each weighing a few tonnes. You want a hefty piece of timber to hold that deck up, even if it does mean you bang your head a few times.
