Naval Contracts are fun on-sea side-missions that you can play in Assassin’s Creed 4, but they don’t come to you without hefty demands and difficult objectives that will require good upgrades.
There are 15 total Naval Contracts that can be completed in the game, but in order to unlock each one, you need to conquer a specific Fort.
Assassin’s Creed 4 Black Flag Naval Contracts
Conquering Naval Forts itself is a grueling and time-consuming process, but it will definitely aid you indirectly in your Naval Contracts, because you’ll be regularly upgrading your ship, and grant you better chances.
Many of the missions will require you to have the penultimate upgrades for your ship. If you can manage to get your hands on Elite upgrades early, then you should be able to go through the more difficult ones with a breeze.
So why would you want to commit yourself to completing all 15 Naval Contracts in the first place? Well, for starters, it’s fun, and you’ll be able to acquire the Sea Legs achievement.
Secondly, they grant you large amounts of money as reward. Thirdly, completing all 15 of the Naval Contracts will allow you to unlock the Golden Flintlock Pistols.
Enough jibber-jabber; let’s start with them contracts:
Naval Contract #1 – An Eye for an Eye
Mission Start: Fort Castillo de Jagua
Requirement: Board the San Lorenzo
Check around to see if the area is clear of other ships, and then approach the San Lorenzo. You should be able to take it out with a set of Heavy Shot Broadsides and a Swivel Gun.
Make sure you are mobile, and circle around her to keep your cannons aligned. Once you do that, she should be weakened considerably. Board her to complete the contract.
Naval Contract #2 – The Law of the Ocean
Mission Start: Fort Contoyyor
Requirement: Board the Hercules
You should have a good set of broadside cannons to get through this mission easily, since there are multiple vessels involved. Four ships accompany the Hercules, one on one side and three on the other.
You need to make a well-timed sweep perpendicular to the direction of the enemy ships with half sail speed, and shoot at all the ships when they come in your line of fire.
Use Swivel Guns and broadside shots for each one of them. The smaller gunboat vessels should sink immediately, but the Hercules will probably remain. Let it advance to you, and once it is close enough circle around and land a few additional shots, weakening it. Board the brig and you’ll finish the mission.
Naval Contract #3 – A Spanish Plague
Mission Start: Fort Eleuthera
Requirement: Sink 3 Spanish Gunboats
This is a very easy mission, since gunboats stand little to no chance against the Jackdaw.
Naval Contract #4 – Driftwood
Requirement: Loot 60 wood
The best place to find 60 wood is schooners. They are quite common in the northern area of the map. Use your spyglass to identify the vessels from afar.
Though it will be quite time-consuming, you will only need a few of these ships to complete the 60 wood requirement. It also helps if you already have a part or most of the required amount beforehand.
Head back to the fort to give it to the merchant.
Naval Contract #5 – Silk on the Waves
Requirement: Loot 30 cloth
This mission is similar to Contract 4, except 30 cloth is a bit easier to find. You will be able to find it in schooners. Once again, use your spyglass to identify which ones carry cloth, and then attack. This should take lesser time than Contract 4. Return to the merchant to complete the contract.
Naval Contract #6 – Contraband
Requirement: Sink one Spanish Frigate and two Spanish brigs.
This is a challenging mission because you’ll be going at it with no stops in between. Try finding lone ships instead of getting into skirmishes against multiple ones.
It is highly recommended that you use Reinforced Hull Armor and Reinforced Mortar/Round Shot Strength. Use the mortars to weaken ships from a distance, and then get close to them to finish them off.
Many ships are way too strong to go head on from the start, so you should be using this strategy with every one of the 3 required to be on the safe side.
Ramming into ships is also a good shocker after a heavy mortar assault. Circle around her after the ram and bombard with swivel guns and heavy shots to finish it off.
Naval Contract #7 – Private Escort
Requirement: Protect the Neptuno
This is another very difficult mission. You will need to defend the Neptuno against waves of enemies. Advanced weaponry and armor are recommended, with high recommendation for refined mortars.
Approach parallel to the Neptuno; for the first wave, two gunboats will attempt to attack her. Take them out with chain shot and swivel guns. Make sure you don’t hit the Neptuno during this stage.
The second wave will consist of three gunboats. Turn to face your guns towards them, and make a slow half sail pass and take them out. The third wave is the hardest of all. There will be two brigs and two schooners coming towards the Neptuno.
