From what I have read the conditions in joining the Royal Navy were far from what stories and media make it out to be. You had a very high chance of death, worked in horrible conditions, and at the very end the government found any excuse to not pay you, which I believe is why many became pirates. So why did people join? Were they conscripted?
I've written about joining the Navy in various roles before:
