you got any more info? Its a bit hard to help with so little:) are you a PC?
I always try to make sure I have at least a little cold iron and silver (even if it's just a dagger of each) and something piercing, something bludgeoning, and something slashing.
yeah its pirates, its gonna be super varied, this isn't the world wound where its demons and more demons with vermin and cultists for flavor:)
as Sterling Archer says "See, this is why i like to play it loose!"
just have fun and try not over think it:)
