Why does Ship Not Found by Name happen?
Searching for a vessel by name on MarineRadar should feel simple. After carefully typing the name and clicking search, nothing appears. The issue of a ship not found by name is one of the most common concerns among users.
There are clear reasons why this happens, and it’s usually not a technical error. Let’s walk through it step by step to better understand it.
How Does Ship Name Search Work on MarineRadar?
MarineRadar uses AIS (Automatic Identification System) data to display vessel details. Every ship that broadcasts AIS data sends information such as
- Vessel name
- MMSI number
- IMO number
- Position and speed
MarineRadar simply displays what the ship transmits. Therefore, if anything is missing or slightly different, it could affect search results.
Why Does Ship Not Found by Name Happen?
Although it may be confusing, there are several common and logical reasons for this issue.
1. Vessel Name Entered Differently in AIS
The crew first manually enters the ship’s name.
As a result:
- Spelling mistakes may exist
- Extra spaces or symbols may appear.
- Abbreviations may be used instead of full names.
If the name you search for doesn’t exactly match the AIS entry, MarineRadar may not show results.
2. Ship Is Not Broadcasting AIS Data
Not all vessels transmit AIS signals at all times.
For example:
- Small boats may turn AIS off
- Fishing vessels may limit broadcasts.
- Ships in remote areas may lose signal.
When AIS data is unavailable, a ship not found by name becomes unavoidable.
3. Recently Changed Vessel Name
Ships can change names during ownership transfers.
In such cases:
- The new name may not yet be updated
- Old names may still appear in records.
- Search results may lag temporarily.
Because MarineRadar relies on live AIS data, updates depend on what the vessel transmits.
4. Vessel Is Out of Coverage Area
MarineRadar collects data from:
- Shore-based receivers
- Satellite AIS sources
However, if a vessel moves outside coverage zones or into areas of poor reception, its data may not appear in searches until the signal returns.
5. Incorrect Search Method Used
Many users rely only on vessel names. However, name searches are not always the most reliable.
Instead, MarineRadar supports:
- MMSI number search
- IMO number search
- Call sign lookup
Using these identifiers often gives faster, more accurate results.
How can a ship not found by name be quickly fixed?
If you face this issue, try the following steps:
- Double-check spelling and spacing
- Remove extra words like “MV” or “MT.”
- Search using MMSI or IMO instead.
- Zoom out on the map to scan manually.
- Wait for the next AIS update.
Most of the time, one of these methods solves the problem.
Why Can't Ship Names Be Guessed by MarineRadar?
MarineRadar never guesses or automatically fills missing data.
Instead, it:
- Displays verified AIS information
- Avoids showing incorrect ship identities
- Updates results only when new data arrives.
This guarantees accuracy and trust, but it may feel restrictive.
When Will the Ship Show Up Later?
Sometimes, a vessel appears after some time.
This happens because:
- AIS signal reconnects
- Data refreshes from satellites.
- The vessel re-enters coverage zones.
Conclusion
Seeing a ship not found by name on MarineRadar doesn’t mean the vessel is invisible or lost. Instead, it reflects how live AIS tracking works. With the right search approach and a little understanding, MarineRadar becomes much easier to use.

FAQs
Q: Why does a ship show on the map but not in search?
The name may be misspelled or different in the AIS data.
Q: Is MMSI search better than name search?
Yes. MMSI and IMO searches are more accurate.
Q: How long does it take for a ship to reappear?
It depends on AIS signal availability and coverage.
