I agree 100% with Garry and Gordon regarding this "pirate's" appearance. IMO he'd make an awesome naval officer to lead a force of pirate hunters!
On the other hand, pirates weren't always outlaws-in-a-boat, but national navies with a policy of disrupting or raiding other people's shipping.
The American navy went to war with Tunisia over piracy in the 1800s. The pirates were the Tunisian navy itself, with a bad habit of raiding European shipping lines.
The British also did a lot of pirate raids against the Spanish.
So, pirates aren't necessarily ragged brigands, patched and unshaven (though this fellow definitely appears to be patched and unshaven....)
