Port Battle Types

Please note that the port battle classifications are defined by ship BR ratings. Be sure to check the BR rating of any ship you wish to use to ensure it qualifies.

Shallow Water
4th Rate Deep Water
Line Ship Deep Water
BR 50 - 75
BR 75 - 300
BR 75 - 600
Shallow water port battles take place where a county capital is classified as a shallow draft port.
Intermediate deep water port battle classification.
The heavyweight class of port battles.

Port Battle Entry

Entry Method

There are two concentric circles (green in diagram below) drawn around the port that are only visible once the port battle opens and the crossed swords battle marker is active. caption

Defense Circle

The inner defense circle is approximately 5 km in diameter. All defending captains must have their ships inside this inner circle to activate the battle marker and enter the port battle instance.

Attack Circle

The outer attack circle is approximately 8 km in diameter. All attacking captains must have their ships outside this outer circle to activate the battle marker and enter the port battle instance. For cases where land may be obstructing a clear view of the battle marker, captains may also click on the port buildings to enter the port battle instance.

Access Priority

First 2 minutes - top 25 captains for each side with the most hostility points.
2 minutes to 5 minutes - any captain with hostility points.
After 5 minutes - any captain.

Wind Conditions

Wind conditions within the port battle instance will be the same as in the open world when the port battle opened for entry and displayed the battle marker. The wind direction shall remain static for 20 minutes and then begin to change as per usual open world behavior. Attackers will need to be especially mindful of the open world wind direction as the port battle start time nears and possibly choose their direction of approach to the attack circle perimeter so as to gain a weather gauge advantage.

Port Battle Instance

The port battle instance is an exact copy of the open world port, with all of its buildings and fortifications. Ships activating the port battle marker will enter the battle instance with the same position and heading as they had in the open world.

Port Zone Maps

Land Fortifications

The port martello towers and forts will fire upon any attacking ships that get within shot range (red circles in diagram above).

Control Zones

Arranged in front of the port are three control zones (gray in diagram above) 1.5 km in diameter. They are designated as 'A', 'B' and 'C'. Their positioning for any given port will always be the same, but are very much dependent on the topography of the map immediately in front of the port. The shoreline plus inlets, islands and peninsulas may result in radically different zone arrangements from one port to the next. Some combinations of topography and zone arrangements may favor either the defenders or the attackers.
Control of a zone is accomplished by simply having more ships within the circle than the opposition, regardless of ship's rating differences. A 5th rate is equal to a 1st rate for determining zone control. The superiority in number of ships must be held for a period of time before control is established. A one ship advantage will establish control over a zone after 120 seconds, three ships in 30 seconds.
The status of the 3 zones are shown at the top of the radar window.
Grey circle = uncontrolled
Red diamond = controlled by enemy team
White square = controlled by your team

Port Battle Scoring

Control Zone Scoring
As described earlier, points are scored for controlling a zone at a rate of 2 points every 5 seconds (24 points per minute). Note that if defenders and attackers each control a zone, those zones cancel each other out and no points are awarded for either. Only controlled zones not matched by the opposition get 2 points each 5 second tick.
Capture & Destroy
Whether boarded and captured or sunk and destroyed, ships are scored as:
Line ships = 40 points
All other ships = 25 points
Fortifications are scored as:
Forts = 150 points
Towers = 50 points
Score Display
The current score of both teams is seen to either side of the zone status indicators at the top of the radar display.

Win Conditions
The side that scores 1000 points first wins the port battle.
The attackers must reach 1000 points within 90 minutes or the defenders win.
