After beginning the contract, we’ll first need to go and find the ship that we need to destroy. If you look at your map, you’ll see that there is a large, green investigation zone to the northwest of our current location. Sail over here and pull out your spyglass to identify the target ship (I found it at coordinates: 430,340).

This ship is a man o’ war that has been heavily upgraded. It has lots of armour and high-level weapons equipped – mortar, heavy shot, chase cannons which will all cause a great deal of damage.

Fortunately for us, it is a pretty slow vessel so if you are able to keep your distance (try to stay just at the max range for your broadside shots) and circle it for a little while whilst avoiding the mortar fire and delivering mortars and broadsides to it from range you should be able to damage it without too much trouble.

With a heavily upgraded Jackdaw, this ship should pose you no trouble.

Once the target vessel has been damaged sufficiently to have it incapacitated, approach it and sink it to complete the mission.
