Would you still legally be able to sail a Pirate brig/frigate or even Man o' War in this day and age for leisure/business?
I know that there are some ships that are used today but they're mainly just used as tour company shit/for tourists and will sail around small areas.
But could you buy yourself one of these ships and sail it for whatever reason you require be it business or pleasure? As long as you had the crew.
Also would you be able to load and use the canons to fend off against opposing pirates?
