Plunder a Hunter Ship in AC4 Black Flag

"Plunder a hunter ship" is an optional mission objective in Sequence 3 / Memory 04: Raise the Black Flag


As you plunder more merchant ships, your Wanted Level will rise and eventually Hunter Ships will start appearing and chasing you down

Plunder one of those to complete this optional objective

Be careful though, Hunter Ships possess superior weapons and a stronger hull than an average ship
