    Everyone is reporting on these ships making it through the strait which is still under Iranian control. Few seem to mention the part in the Gulf of Oman where the US is actually implementing its blockade. The poster child, Rich Starry, mentioned in the article, did this a few hours after clearing the strait, still far from the Arabian Sea:

    Marine tracker timelapse showing RICH STARRY travelling southeast out of the Strait of Hormuz, halting and showing stale data for around 3.5 hours, and then returning back the way it came at speed.

    That sure doesn’t look like a ship breaching a blockade without incident.

    It’s too early to say how this will play out on a larger scale but for these specific ships a lot of reporting is really fucking misleading at the moment.

      So you think a ship that was moving at maybe 5 knots/hr instantly turned around and in less than 30 minutes accelerated past 50 knots/hr?

        I don’t know where you’re getting any of that from. It was travelling at 8 knots before and after the turnaround. The bit in the animation where it slows and drifts almost due south is actually marinetraffic not having AIS data for that period so it just interpolates between the two known positions. Maybe I should have made that clearer.

        That turnaround period is also close to 3.5 (edit: 2.5) hours, not 30 minutes.

        According to the same data the ship is now close to the Strait of Hormuz that it passed through yesterday; it seems pretty clear it did not get where it wanted to go.

          According to the data shown in the gif, the turn around took exactly 30 minutes, wherein it teleported at least 20km.

          So what’s more likely, the AIS data was missing the entire time and its real position is on the same course, or it did an impossible turn as shown by the data provided?

            The gif shows no data (dimmed icon) from 08:49 UTC to 11:10 UTC so I had my maths wrong and it’s 2 hours 21 minutes, apologies. Still a lot more than 30 minutes. The AIS data also generally comes in less frequently than every minute so there’s some unreliability there.

            As I said, according to the current data the ship definitely kept going back up towards the Strait since I posted, so what’s more likely, it kept going on its current course and spoofed its AIS for nearly 12 hours, or that it turned around?

        The fact that you are measuring speed in knots per hour invalidates your point.

        Please use a correct measurement, and try again.

            I find that reasonably unlikely, unless it is a naval ship. I don’t think cargo ships go that fast unless empty, and highly motivated. Possibly not even then.

            Do we have a reliable source for this data?

              Most naval vessels can do just over 30, if that. Cargo vessels spend most of their life below 10.

              50 knots means there’s some fuckery afoot.

                Sure, but the gif doesn’t show 50 knots. The gif doesn’t show any speed actually, so I really don’t know where the 50 number comes from. But on the tracker the speed was 8.1 knots. Fast for a tanker, but totally believable.

              My source is marinetraffic.com. Other AIS trackers also corroborate it.

              From the sounds of it the OP and most other articles are based on similar armchair research looking at trackers so I think it’s about as reliable as we’re going to get.

              I’m being accurate. “Knots” is “nautical miles per hour,” as you correctly described.

                All you’re doing is being a grammar nazi to someone who at most said the equivalent of “$30 million dollars”, which is technically, thanks to the dollar sign, “thirty million dollars dollars”.

                You knew what they meant. I knew what they meant. Everyone knew what they meant. There was absolutely zero ambiguity, so you just come off looking like a prick.

                If we are being really pedantic. Knots is a measure of distance, and the fact that people have been using that wrong for several centuries does not turn a rope tied at one point into a time-changing object.

            I think there point is that knots is not a measurement of distance over time so you can’t technically travel in knots per hour.
