About the Game
Take full command in this deeply immersive, large-scale maritime simulation designed for players who value precision and authenticity. Each vessel is operated through detailed, true-to-life systems inspired by real ship operations, without relying on oversimplified mechanics or arcade shortcuts. From managing propulsion and navigation to responding to environmental forces, your success depends on skill, awareness, and control. Built with simulation enthusiasts in mind, this experience offers a focused and rewarding approach to mastering life at sea.
Professional Ship Simulator delivers deep hydrodynamic realism, including propeller torque, bank effect, wind and current drift, anchor behavior, and line tension. Operate fully simulated onboard systems, from power generation and transmission to navigation tools like Radar (with AIS/CPA), sonar, and radio communication. Ships react physically to their environment, featuring hull damage, flooding, and simulated interaction with mooring and towing systems, including wing control stations on larger vessels.
Operate under constantly changing conditions with a full day/night cycle and optional real-time weather data. Dynamic systems simulate moving storm fronts, wind, currents, and sea states including fog, rain, snow, and rough seas which directly affect navigation and ship handling. The sea remains alive with AI traffic, from open-water shipping lanes to dense harbor operations, creating constantly evolving navigation challenges.
Every swell, crest, and crash is modeled using realistic physics, creating a living sea that constantly challenges your ship handling skills. From gentle rolling tides to powerful storms, the water behaves dynamically, affecting speed, stability, and navigation in a way that feels true to life.
Command a growing fleet ranging from small service vessels to large commercial ships. Start with guided tutorials or take on structured missions to earn credits, expand your fleet, and acquire licenses as you progress from a small harbor operator to a professional captain.
Available Ships:
Tugboat
Fishing trawler
Rescue vessel
Offshore ship
Yacht
Container ship
Bulk carrier
LNG tanker
Cruise ship
Explore large-scale environments based on real-world geographic data, including the Island of Rügen (60km x 120km) and the Strait of Dover (140km x 140km).
Authentic seamarks, navigation lights, and over 40 harbors create a believable maritime infrastructure, supported by dynamic harbor activity, wildlife, and dense coastal detail. A tile-based, moddable map system ensures long-term expandability.
Engage in a wide range of professional activities, including cargo transport, ferry operations, fishing with sonar, and offshore logistics. Perform specialized tasks like tug assistance, buoy maintenance, rescue missions, and firefighting. Each mission type is built on realistic systems and requires precise ship handling under real conditions, whether in structured game modes or during free exploration in the open world.
Modding Support (Coming Soon)
Modding will not be available upon launch into Early Access, but is strictly planned to be integrated very soon!
Enhance the game even further with custom ships, missions, and scenery extensions, as well as sound replacements and flags, allowing for a community-driven expansion of the maritime experience, all via Unreal Engine integration.

Official update history
Our first Early Access patch is here! The main focus of this update is addressing several of the most important issues reported since launch, especially crashes and nautical chart loading, while also bringing gameplay, Career, AIS and world improvements.
🛠️ Stability & Crash Fixes
• 🔐 Changed debug log encryption after identifying it as a possible cause of rare crashes.
• 🌐 Replaced the previous HTTP request implementation after identifying rare response-related crashes, especially for players in some overseas regions.
🔎 Known Issue – Ship Handling Tutorials
• Ship Handling tutorials may occasionally stop progressing. Especially when a step is executed already before the step happens.
• If this happens, please send a bug report with Ctrl + Tab immediately after the issue occurs. Bug reports now include your current mission and Career Training state, helping us identify and fix the cause faster.
🗺️ Nautical Chart & Map Fixes
• 🌍 Fixed an issue where the nautical chart could fail to load when the Windows user path contains special characters.
🆕 New Scenario
• 🚢 Added RoPax Arrival at Dover, a new scenario featuring the RoPax ferry arriving at Dover during heavy weather conditions.
• 🏷️ The RoPax ferry company is now named Dover Ferry XPress, with initial support added for map-dependent company names.
🚢 Ships & Gameplay
• 🛟 Fixed an issue where the Rescue Cruiser daughter boat could not be launched.
• 🚤 The Rescue Boat is now available in the Open World vessel selection menu.
• 👤 Fixed the incorrect head / “conehead” shadow visible on the character in First Person View.
📡 AIS & Navigation
• 🟡 Selected AIS targets are now displayed in yellow.
• 📏 AIS target size now adapts to the selected range.
🧑✈️ Career & Tutorials
• 📝 Career tooltips now automatically adapt depending on whether the selected item is a Training, License Check or Vessel Purchase.
• 🛟 Added additional Man Overboard messages during the first License Check maneuver.
• 🐞 Bug reports created with Ctrl + Tab now include additional diagnostic data about active missions and Career Training progression. This will help us better understand and resolve progression issues reported by some players.
🌍 World & Visual Improvements
• 🏗️ Improved the map boundary around Wolgast to prevent vehicles from travelling behind the playable level border.
• 🪜 Fixed incorrect collision on several harbor stairs.
• 🏠 Fixed invisible Harbor Shuttle text at the Ralswiek residential building.
