Pirates or the Trading Company — which side will you choose?
Features
Destruction simulation. Ship hulls are quite literally built from individual planks. Planks break under cannonball hits, leaving holes exactly where the shot landed. If your hull has been breached and your ship is taking on water, strike back by breaking the enemy's mast to stop them from maneuvering.

Firearms. If an enemy gets too close, bleed their crew dry with well-aimed shots from a musket or pistol. But don't forget to take cover while reloading, or you'll take a shot in return.

Melee weapons. When you close in on an enemy side by side, grab your saber and board their ship — sow chaos in the enemy ranks. If they fight back, don't stand still: parry their blows and keep moving.

Different sails, different speed profiles. Square sails give your ship good speed with a tailwind or crosswind, but are useless against a headwind. Fore-and-aft sails stay effective at sharp angles to the wind, but perform worse with a tailwind. Think ahead before you turn, or you may lose speed at the worst possible moment.

Your crew helps in battle. Sailors fire the cannons, shoot muskets, and defend the ship against players boarding it. Your crew is limited, and when there is no one left to fight, the ship is considered defeated.

Command your crew. Assign their duties for maximum efficiency. Order the crew to take the helm, and you can rest easy knowing the ship won't be left without steering.

Co-op, PvP and PvE — all three modes are available. When you create a room, friends can join it and take one of the sides of the conflict.

Campaign mode adds a strategic layer. Your goal is to completely disarm the opposing side by capturing its shipyards and destroying its ships. Co-op, PvP and PvE are also available in this mode.

Campaign mode
The world map contains ports of different types. At the start, each side owns its capital ports, which have shipyards, trade income, and the ability to recruit missing crew after a battle.
To build ships, you need income from the trading ports under your control. Other ports let you recruit sailors, while ports with a shipyard let you build vessels.
Each turn you can move your ships one at a time or two at a time to any neighboring port, until you run out of movement points, which are restored every new turn.
When two opposing fleets meet, you can enter the battle and test your strength and skill, or choose auto-battle. The defending side can weigh anchor with up to two ships, and they will join the battle.
If there is no chance of winning a battle, a light ship can retreat to the nearest allied or neutral port, provided its speed is higher than that of the attackers.
The maximum number of ships in a port is 6. If the enemy has dug in at their last port, you can take it by siege: bring your ships closer and attack two vessels at a time in a single turn. If your fleet is stronger, the defender will eventually either run out of crew or lose all their ships to sinking.
At the start of every turn, the crew reserve available for hire is replenished in each port. At the same time, ships stationed in those ports can replenish their crew. If the siege isn't finished within one turn, the defender may receive reinforcements.
The loser is the side with no ships and no ports with a shipyard left.
