FAST SEARCH

You can use this tool if you know the IMO number or the MMSI code or the ship name (or a part of it).

The IMO number must be 7 digits long and follow some precise rules (not all 7 digits numbers can be an IMO).

The MMSI code must be 9 digits long. Remember that IMO-MMSI association may be wrong as reported by IMO organization in a recent issue.

Fast search works also on current and former names and their known aliases and operates as described below.

If you write lion the system will return all names containing lion (ex: sealion, lioness, billion, lion dream, etc.).

You can also use the character * as jolly.

If you write sk*ser the system will return all names containing sk and ser (ex: maersk server, franciska fisser, etc.).

You can use more than one jolly, for example se*po*1 will return seeponton 10, alpha serviport 1, sevastopolets 1123, etc.

As the results list is always limited to the first 100 vessels found (ordered by IMO), if you are looking for a vessel with a very common name,
you can use the - character in the first position.
For example, if you are looking for a vessel named sea you must use -sea else system will return you a huge list.

And again: if you are looking for an won no.515 and you are not sure if the name contains or not spaces and the string "no.",
you can use -an*won*515.

ADVANCED SEARCH

The advanced tool allows the search by name (only current name), flag, ship type, gross tonnage, deadweight, ship status, call sign, built year, builder, manager and owner.

All text fields allow the use of the character * as jolly, as described above for the fast search tool.

SHIPS DATA

Data update is a very huge work and 24 hours per day are not enough to validate all daily changes before publish them.
Changes are so stored into a "raw database" waiting the validation.

The "last update" info shows, for each vessel, the data of the last update. If you believe that something is changed, you can use the check for update tool, when available,
to start the validation process yourself or the request an update to ask us to prioritize the ship.

The vessel page has also a feedback tool: use it if you have doubt about data or if you need other info about a vessel.

Look at "statistics" page to some further explanations and to know the actual database consistence.

PHOTOS

The "photos" page contains the personal portfolio of each Contributor, always updated.

The vessel page has a upload a photo tool: use it to send us a photo of the vessel. Uploaded photos will be resized, cutted and published asap.

Remember that GT stores only one photo per ship, usually the best available.

Remember also that photos are always owned by their Authors and protected by international copyright.
