If desired, get harpoon upgrades, harpoon storage, strength, and extra armor to make this process easier. Sail to a Killer Whale hunting location (for example, coordinates 537, 340 on the world map). After a deck hand announces the presence of a whale, Kenway will be sent with a harpoon to hunt it. Harpoon the whale and follow it, being careful when it dives. It will eventually surface again on the horizon and run at your boat. Harpoon it again to avoid taking damage. Repeat the process until the whale's health is taken down to unlock the achievement.

Immediately pause game play, select "Reload", and reload the game from the last checkpoint. You can now pickpocket the Templars again. Repeat the process until you collect at least 100,000 Reales.
