Looking back through history we know of the sailing ships and how they were crewed, RN very often with press ganged crew.
I wonder how many died as a the result of falling from the shrouds?
Young lads as young as ten I have read sent up to furl or unfurl the sails.
Most bare footed on that rigging in all manner of weathers and ships pitching and tossing in heavy seas.
Some with very limited experience yet having to do all the same work.
Worst I have ever had is a falling off a ladder ashore
