Advertising and partner disclosure
The free pages are paid for by advertising, partner links and Pro subscriptions.
Advertising
Free pages show ads served by Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other sites. Visitors in regions that require consent see a consent choice before personalised ads load. You can manage ad personalisation at Google Ad Settings. Pro subscribers see no ads.
Partner links
Some pages link to products we think are relevant, such as charting platforms or hosting for trading software. If you sign up through these links we may earn a commission at no extra cost to you. Partner links are marked as such, open in a new tab and carry a sponsored attribute.
What partners cannot do
- Pay to change any figure, count or calculation on this site.
- Buy placement inside Tanker Watch data or calculator results.
- Review or approve guides before publication.
We do not accept partnerships with brokers or signal sellers.
