Members may be aware from earlier threads that the supplier of the Additional Information, grosstonnage.com, closed down early last year. It is now clear from the owners that that is permanent. The information was therefore frozen at that point - and there is no facility to correct or update it.
Attempts have been made with the site-owners to find another source of credible data which could be linked to Shipspotters, but without success.
Some members will recall that there was already concern about the accuracy of some Grosstonnage data even when it was running, and the added update link was introduced to deliver corrections direct to them. Shipspotting Admin have never had the facility to amend Grosstonnage data directly. In recent months, as the data has become more and more out of date, not only have members increased reports of wrong data (in the belief that we could amend it), but also the number of serious complaints from shipowners about wrong data has increased, and could only have got worse.
The owner/manager fields have therefore now been deleted. The shipbuilder field seems to have gone as well and we will try to get that put back, despite its errors and limitation to the latest shipbuilder on the site concerned, though we will still have no ability to amend it.
