On this page of the Assassin's Creed Valhalla trophy guide, you will learn how to unlock the Row Rage trophy. This achievement is obtained for ramming and destroying 5 boats in 2 minutes by ship.
There is a low chance to unlock this trophy by accident because 2 minutes is not much time to sink 5 boats in a row. The choice of location may also be problematic. In many places, you will only find single boats, and this will be insufficient for the trophy.
The ideal place to unlock this achievement is shown in the picture above - it is a water body in the southern part of the Lincolnscire region in England. Get there on your own boat and before you start, save the game so you can easily repeat the process if necessary.
After reaching the area marked on the map, you will notice small boats that are used by the inhabitants of the land. They can be close to each other (an example is shown in the picture) or at a slightly greater distance from each other. Try to reach them in such a way to make as little unnecessary moves as possible.
Don't forget to raise the sails when moving towards the boat you're about to ram. Sometimes, after a collision, the sails will be automatically lowered. Quickly hold down the raise sails button and continue ramming until the boat is sunk.
Try to get to the next boats as soon as possible, as the "invisible" 2-minute meter will start when the first boat is destroyed.
