- ostranauts not fit our docking facility usually points to a physical berth or geometry problem.
- Check the target and confirm you are approaching a compatible station, ship, or airlock.
- Match speed before clamping, keeping docking velocity below 100 m/s whenever possible.
- Align the airlock with the facility connection point instead of approaching at an angle.
- Use a smaller berth or another docking target when the ship cannot physically fit.
ostranauts not fit our docking facility: What It Means
The ostranauts not fit our docking facility message generally indicates that your ship cannot use the selected docking point as configured. In most cases, this is a physical compatibility issue rather than a simple fuel, oxygen, or navigation failure. The berth, airlock, clamp, or approach corridor may not provide enough room for your current hull layout.
Docking in Ostranauts depends on more than reaching the correct coordinates. Your ship must approach the target with a suitable orientation, bring relative movement under control, and place its clamp near the target’s airlock or docking connection. A ship that is too large, badly angled, or aimed at the wrong facility can fail even when it appears close to the station.
Video Highlights:
- Character creation leads into the first ship and station tutorial.
- The tutorial teaches permission to undock, relative velocity, and ship controls.
- Safe docking practice emphasizes matching speed and approaching the target airlock.
- Salvage operations depend on returning to a station and docking safely.
| Likely Cause | What You Notice | Best First Check |
|---|---|---|
| Ship is too large | The facility rejects the approach despite correct navigation | Try a smaller berth or another target |
| Wrong docking point | The ship is near the station but no connection is accepted | Select the actual airlock or clamp point |
| Poor alignment | The clamp passes beside the connection | Rotate until the airlock and clamp face each other |
| Excessive relative speed | The ship overshoots or collides during approach | Use match speed and reduce velocity |
| Damaged ship systems | Controls or movement respond slowly or unpredictably | Inspect power, thrusters, and navigation resources |
When the game says the ship does not fit, do not immediately assume the navigation console is broken. First inspect the physical relationship between your hull, the docking point, and the available berth.
The most reliable approach is to separate facility compatibility from pilot control. If the game refuses the ship before you reach the connection point, the facility may be unsuitable. If the refusal happens only during the final approach, alignment or relative velocity is more likely.
You should also consider recent ship modifications. Adding floors, walls, storage, external cargo netting, tanks, or other components can change the shape of the vessel. A design that originally fit a station connection may become awkward or impossible to dock after expansion. Keep important access points clear while building, especially around the clamp and airlock side of the ship.
Docking Compatibility Checks
Before trying another approach, confirm that you are targeting the correct object. Ostranauts contains stations, derelicts, ships, and facility structures that may look similar from a distance but serve different purposes. A nearby surface or hull section is not necessarily a usable docking point.
The tutorial route establishes a useful pattern: obtain permission to undock, control the ship with the navigation console, locate the target derelict, match speed, align the clamp with its airlock, and clamp only when the approach is controlled. The same sequence applies when returning to a station, although the station’s available facilities may impose different physical limits.
Target Selection
Choose the intended station, ship, or airlock connection. Do not rely only on visual proximity.
Hull Clearance
Check whether added walls, floors, tanks, and external equipment make the ship too wide or obstruct the docking side.
Approach Control
Reduce relative movement before the final approach. A correct target can still become unsafe at excessive speed.
| Check | Correct Condition | If It Fails |
|---|---|---|
| Target | The selected object has a usable docking connection | Select the facility or airlock directly |
| Ship profile | The hull and external parts leave clearance | Remove, relocate, or avoid the obstructing section |
| Docking side | The clamp faces the target connection | Rotate the ship before closing distance |
| Relative velocity | VREL is low and controlled | Match speed, then make small corrections |
| Lateral movement | VCRS is near zero during a straight approach | Correct sideways drift before clamping |
| Resources | Power and navigation supplies are available | Refuel or repair before repeated attempts |
In the navigation display, VREL represents relative velocity toward or away from the target, while VCRS represents relative velocity perpendicular to it. For a clean approach, reduce both values instead of attempting to correct orientation and speed at the same time.
A practical rule is to approach slowly enough that you can stop without relying on a last-second maneuver. The tutorial recommends docking below 100 m/s, and keeping movement below 200 m/s near stations or derelicts gives you more room to recover from mistakes. These values are safety guidance, not a guarantee that every facility can accept every ship.
A failed docking attempt can become a collision, hull breach, or injury event. If the ship is still moving too quickly, pull away, match speed again, and restart the approach instead of holding the clamp button.
If your ship repeatedly fails at one facility but docks elsewhere, treat that as evidence of a berth or geometry limitation. If it fails at every target, inspect the ship’s control systems, power, fuel, and navigation setup before rebuilding the hull.
Step-by-Step Docking Fix
Use this sequence when the docking facility rejects your ship. It is designed to identify the problem without wasting fuel, damaging the hull, or repeatedly colliding with the target.
Select the Actual Docking Point
Identify the station, derelict, or ship you intend to use. Move the navigation target onto the facility’s usable airlock or connection area rather than selecting a random point along the outer hull.
Inspect Your Ship’s Docking Side
Check the side containing the clamp and airlock. Look for recently installed walls, floors, tanks, racks, or cargo equipment that could block the approach or make the ship too large for the berth.
Match Relative Speed
Use the navigation controls to reduce movement toward the target. Bring VREL down before closing the final distance, and correct VCRS so the ship is not sliding across the docking point.
Align the Clamp and Airlock
Rotate the ship until the clamp is facing the target connection. Make small corrections rather than turning sharply beside the station or derelict.
Clamp or Change Facility
Attempt the connection only at a controlled speed. If the message still says the ship does not fit, retreat safely and try a larger or more suitable docking point instead of forcing the same berth.
| Phase | Recommended Action | Avoid |
|---|---|---|
| Setup | Confirm power, thrusters, and navigation supplies | Beginning with empty tanks or damaged controls |
| Approach | Keep the target centered and reduce relative speed | High-speed corrections near the facility |
| Alignment | Face the clamp toward the airlock | Approaching sideways or diagonally |
| Final distance | Use small thrust inputs | Holding acceleration until contact |
| Failure recovery | Back away and reassess the berth | Repeating the same collision attempt |
After a successful connection, use the station or ship access point carefully. If you are returning from salvage, keep your suit and air supply in mind before crossing an airlock. A docking problem can create a second emergency if the character enters an unsafe area without adequate protection.
The same caution applies to damaged vessels. Repairs to power infrastructure can restore doors and access, but a ship with weak hull sections, poor pressure control, or depleted batteries may not be ready for a long salvage cycle. Docking is only one part of a safe recovery plan.
Pull away, pause the approach, inspect the target and ship profile, then retry at lower relative speed. Changing the facility is often faster than rebuilding a working ship around one berth.
Ship Design and Facility Fit
Preventing the error is easier when the ship is designed with docking clearance in mind. Early vessels are usually compact, so the first problem often appears after adding storage or salvaged equipment. Treat the docking side as a functional workspace rather than filling every available tile.
External equipment can be valuable, especially during shipbreaking. Thrusters, doors, pumps, and oxygen tanks may sell well when repaired, but temporarily attaching or storing parts near the docking side can interfere with future approaches. Move salvage into a hauling zone or a clear storage area whenever possible.
Keep Clear
Preserve open space around the clamp, airlock, and approach direction.
Build Carefully
Place new floors and walls away from the primary docking path.
Store Salvage
Use racks, hauling zones, or cargo netting instead of blocking access points.
Test Often
Perform a short undock and return trip after major structural changes.
| Ship Change | Docking Risk | Safer Practice |
|---|---|---|
| Wider hull extension | May exceed berth clearance | Expand away from the docking side |
| External cargo netting | Can obstruct the approach | Keep it outside the clamp path |
| Added tanks or pumps | May change the ship profile | Install them where they remain accessible |
| Salvaged doors and walls | Can block movement or visibility | Store them in a hauling zone |
| New airlock layout | May confuse the intended connection | Mark one primary docking route |
Zones also help keep the ship manageable after a successful docking operation. A hauling zone can pull marked items into a designated area, while a barter zone can organize goods intended for sale or purchased supplies. Forbidden zones can prevent crew from entering dangerous or unfinished areas.
Crew permissions matter as the vessel becomes more complex. Crew members need access to the places where they work, but they should not be allowed to open airlocks or cross exposed sections without proper protection. A tidy ship is easier to dock, repair, pressurize, and operate during fast-forwarded time.
A compact, clearly organized ship is easier to recover than a larger vessel with blocked access points. Add structural improvements gradually and test docking after each major change.
For early progression, prioritize a reliable docking path over maximum cargo volume. A smaller ship that can return safely, sell salvage, pay bills, and refuel provides a stronger foundation than a larger design that cannot use the station facilities you depend on.
Docking Troubleshooting Checklist and FAQ
Use this checklist before leaving a station or attempting a difficult return. It covers both the physical fit problem and the risks that can turn a docking attempt into a wider survival crisis.
Before You Dock:
- Select the correct station, ship, or airlock connection
- Check the clamp side for blocked or oversized components
- Reduce VREL and VCRS before the final approach
- Keep docking speed below 100 m/s whenever practical
- Confirm power, navigation supplies, hull condition, and airlock access
| Symptom | Most Likely Explanation | Response |
|---|---|---|
| Rejected immediately | Facility may not support the ship’s profile | Try another berth or target |
| Passes close without connecting | Clamp is not aligned with the airlock | Rotate and approach again |
| Overshoots target | Relative speed remains too high | Match speed earlier |
| Crew refuses access | Permission, zone, or safety restriction | Review roster permissions and zones |
| Docking succeeds but recovery is unsafe | Pressure, suit, or hull problem | Repair, cycle air, and verify protection |
Q: What does “not fit our docking facility” mean in Ostranauts?
It usually means the selected berth or connection cannot accept your ship’s current physical layout. Check the hull profile, docking side, airlock position, and nearby obstructions before blaming the navigation controls.
Q: What speed should I use when docking?
Keep the approach controlled and aim for under 100 m/s when docking. Near stations or derelicts, staying below 200 m/s while maneuvering gives you more time to correct alignment and avoid collisions.
Q: Why is my ship close to the station but still unable to dock?
Distance alone is not enough. The clamp must face the usable airlock or connection point, and relative movement must be low. Reduce VREL, correct VCRS, and approach the actual docking point.
Q: Can ship upgrades cause the docking facility error?
Yes. Added walls, floors, tanks, racks, cargo equipment, or other external parts can change the ship’s profile and obstruct the docking path. Test the ship after major structural changes and keep the clamp side clear.
For current game information and developer updates, check the official Blue Bottle Games Ostranauts page, accessed August 4, 2026. The page is the best place to verify changes that may affect docking, ship construction, or station behavior.
The core lesson is straightforward: treat docking as a controlled physical maneuver, not a single button press. Confirm the facility, preserve clearance, match speed, align the connection, and change targets when the berth is incompatible. With that routine, the ostranauts not fit our docking facility message becomes a useful warning rather than a mystery.
If a facility rejects your expanded ship, protect the vessel first. A safe retreat and alternate berth usually preserve more progress than a forced docking attempt.
