All trainee navigators are taught never to trust a marine chart until they have checked the survey date and the date of the last correction (update). Searching the internet often brings up very relevant pages BUT after digging around you find they were created and/or last updated years ago!.....somtimes this is fine.....but often you are seeking the latest information.
Could the date of origin/last update by extracted from the page data and shown in the Search Results listing....or perhaps as a choice in the DuckDuckGo settings menu?
