It was mentioned here that ENI number was searchable on the site, but the function is not implemented fully.
ENI number on the page is not "clickable"; ENI number entered in the "Search" field produces no results.
At the same time, vessels are obviously grouped according to their ENI number, showing various photos of the same ship with the same ENI number, but the photo page does not have the same "More of this ship" tab with photos, like the pages of ships with IMO numbers.
