What is the public sea-service profile?
An opt-in web page on bridgedeck.app, at your own link under /crew/, that shows the headline numbers from your logbook. In the app's words, it is “a shareable web page with your headline sea time. No vessel names, ever.”
What does my profile show?
Your name (or only your initials, if you prefer), your rank and the year you went to sea. Then your sea days, days aboard, nautical miles, voyages and number of vessels, and your sea days split by tonnage class: under 200 GT, under 500 GT, under 3,000 GT and unlimited.
What does it never show?
Vessel names, IMO numbers, ports or dates. The page shows totals only, and it says on it that the figures are self-declared sea time shared by their owner.
