What the developers have to say:

Why Early Access?

“Sea Trials is a long age of sail tradition. Captains of that time had a chance to test their vessel and provide feedback to the Admiralty on what needs to be changed to make the ship perform better. Extensive sea trials are required by the Admiralty to fully test if the ships in the game are seaworthy and ready for fighting.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access until core features of the game are finished and polished.”

How is the full version planned to differ from the Early Access version?

“The game is in alpha. We plan to focus on the following during the Early Access
  • Improved User Interface
  • New ships
  • More features like production buildings, officers and better crew management and many other exciting things.

for more information please visit our forums.”

What is the current state of the Early Access version?

“Excellent age of sail combat representation
Basic crafting
Basic trading
Basic conquest
Multiple playable nations
Large variety of age of sail vessels

User interface is purely technical and will be improved once more features get into the game.”

Will the game be priced differently during and after Early Access?

“Price will go up when Early Access ends.”

How are you planning on involving the Community in your development process?

“Naval Action community has been involved in the development from the start. We are very proud to say that many features the game has were proposed and designed based on community ideas. We plan to continue doing so going forward.

To share your voice and propose features please visit our Steam community forums or our company forums located here

The day of days has come - and we are getting close and closer to release.
Patch will be deployed today on 31st of October.

This is the biggest patch we delivered to date so expect problems and issues - they will be fixed one by one.

  • It is impossible to describe the multitude of changes in this patch so the list will be short and will just cover areas of changes
  • New bugs and loopholes - please report issues in designated topics or in this topic
  • Updated port user interface. Everything has changed. Just like with all interface updates it will feel weird and sometimes wrong. But it is a much better UI and most importantly it is better for localization
  • Economy has moved to historical currencies
    • reals - silver dollars
    • doubloons - double escudos - gold goins
    • pvp marks and combat marks have been abandoned. Combat marks will be converted to reals - pvp marks turn into doubloons
    • denomination has been applied to all prices (approximately 25 to 1)
      • please report if we missed something in this area
    • 2000 doubloons will be issued to all captains as a timed redeemable for 14 days.
  • Holds contents have been updated for
    • combat ships
    • traders
    • sealed bottles
    • chests
    • all vessels can sometimes carry crew pay (military ships) or results of trading in doubloons (traders) and in good amounts
  • Ship capture rules updated
  • Previously you could not capture imported ships and could not capture 1-4th rates on the PVP server
  • New rule is the following (mostly concerns the War (caribbean) server
    • You cannot take non captureable ships to the open world but you can use them in the instance
    • this means you can capture all ships for sailing in the current battle instance
      once you exit the instance non capturable ships will be taken over by the admiralty (with hold)
    • Please make sure you dont exit in the imported ship or non capturable ship to the open world if you have valuable things in the hold
    • To receive a reward for that ship sink it in the instance transferring to a capturable ship
  • New missions
    • Hunt and search and destroy - to find and destroy ships in the open world
    • Weekly challenges
    • kill missions (former combat orders) now have difficulty levels and increased rewards
    • bot distribution changed. certain regions now have lineships (like hispaniola) some regions have 5th rates only.
  • Mission class and difficulty now depend on ports
    • Starting ports have lower level missions and easier missions
  • Insurance has been added to all crafted ships
    • you must fight bravely and do not give up the ship (sink) to receive insurance
  • Tow to port now only works if you are really stuck in the open world
  • Economy has been streamlined
    • redundant materials removed (conversion tables were provided before)
    • resources weights and prices changed
    • building production limits have been greatly increased for lvl 3 buildings
      • e.g lvl 3 building now allow production approximately similar to 5 level 3 buildings before the patch.
      • as a result euro traders permits were removed from the caribbean for testing
    • prices for buildings were adjusted based on complexity of production
    • current buildings were closed and wiped for all players (costs to reopen was added to redeemables)
    • new buildings introduced
    • outposts now charge for passenger transportation
  • Admiralty prices updated
    • book prices for high level ships generally increased (because of ample supply of doubloons from activities)
    • ship notes prices now correspond to the alternative of crafting that ship (a lot higher)
  • Max BR limit for shallow port battle is now 110 (which makes Prince the highest BR ship that can enter port battles)
Known issues
  • Сhallenge events will start on Monday (light, frigate, lineships)
  • Economy and prices are new and might require several iterations to stabilize and tune
  • Clan leaderboard table does not work as intended and will be updated later - it only shows port battle oriented clans[/i]
  • Very rare issue of corrupted items locking the exit from ports can still happen - but we have added the automatic deletion of such items and added additional logs to find more cases of such issue. If you cannot exit from port or sell a ship it is because one item in hold has become corrupted - please let us know when this happen in support section or by f11.

Please provide feedback in this section (3 topics are pinned on top and focus on interface, economy and missions)

Next steps

We plan to stabilize the patch in several iterations and continue work on localization in parallel

Next big patch will focus on localization.

Official promised languages will be localized by GL, but we will provide the tool to change the language to another if it will be localized by the community (access to language file will be provided and players will be able to replace it with their own).

Important information

Doubloons for shipyard lvl 2 and lvl 3 will be delivered to redeemables or directly to money chest by the end of the day today. Spread the news. We wanted to deliver the update during maintenance and not wait until the evening.

About This Game

Naval action - open world multiplayer sandbox

Naval Action is a hardcore, realistic, and beautifully detailed naval combat game immersing players into the experience of the most beautiful period of naval history - when sailing ships ruled the seas.


Exciting bugs – Because its still alpha we have an interesting selection of annoying, strange, and sometimes wonderful bugs. We are squashing them one by one, but it's Caribbean - they will keep coming for quite some time.

Enormous open world – Large open world, recreated based on 18th Century maps, historical harbors, positions, and town names. We do not believe in the various modern hand-holding markers, thus player position is not shown on the map: you will have to navigate yourself using compass, sun or landmarks. PS. battles are instanced to allow extremely complex sailing and fighting calculations for 50 ship battles.

Freedom – Build ships, trade, sink enemies of your nation. You can attack anyone almost everywhere. Remember that every action could have consequences. So don't attack everyone - or you will become a pirate. Conquer almost every port in the Caribbean, but remember! other adventurous captains will try to ruin your plans.

Beautiful ships – Accurate hull models, sail plans, guns, internal upgrades, historical speed, turning and heel performance. Ships from small cutters to large 100+ gun 1st rates will allow the player to experience every possible role of the Age of Sail period.

Realistic sailing – Advanced wind and physics model provides for realistic portrayal of ship’s performance in the age of sail. Yard angles, ship angle to wind, fittings and ship condition affects speeds and turning rates. Correct tacking, boxhauling, clubhauling and other elements of the age of sail sailing are possible. Hidden ship characteristics will allow to gradually uncover potential of the vessel – every ship in game will be unique.

Historical gunnery - Realistic ballistics and cannon performance of the period. Every cannonball is tracked in the air and after it hits the target. One shot can hit the stern, damage the rudder, then hit the cannon carriage, injure crew, ricochet from the floor and hit the opposite side. Listing and wind affects the shooting distance and will require change of tactics.

Weapons - All major types of naval artillery are implemented: from long guns to carronades. Fort and land batteries will provide support during port battles. Mortars are coming soon.

Damage model - Leaks, structural damage, torn sails, demasting, raking, fires and all other hazards that were possible in that era. Damage is positional: hit the gun and you might destroy it. Gunnery crews are placed deck by deck. Shot can pass through the balcony, ricochet of the gun, hit a crew member and then fly out of the gunport splashing into the water. Armor thickness and wood type is implemented and at extreme angles cannonballs will ricochet from the hulls.

Community driven development - Players actively participate in development and many elements of the game have already been implemented based on the player feedback. Content is immediately given out to players for testing and improvement. Share your thoughts in comments or on the forums.
