"Incapacitate the Man O War" is a mission objective in Sequence 8 / Memory 01: Do Not Go Gently
Walkthrough
Go to full sail to get within range. Use the Telescope to mark it so you can see the range between you and it. Use Mortar fire to weaken the Man O War and get some damage in on the other ships. Still, focus on the Man O War. It will not take too much with a good mix of fire.
