Yes.
However, these are small boats and they would not be in the middle of the gulf because: a) they are littoral boats and stay close to shore because they operate there, b) traveling from Kuwait to Bahrain keeps them well south of the center of the gulf, and c) small boats avoid the middle of the gulf because the middle is a huge shipping lane with huge ships coming and going.
When I was on a Navy ship in the gulf back in the day (JTFME), we has USN ships everywhere. . . not so much today. That is why I think the Navy simply couldn’t get there in time and I think the Iranians seized them in international waters as they did not drift north into Iranian waters. Why? Because the tide moves in and out of the gulf (southeast and northwest). https://www.youtube.com/watch?v=iZl8fVHWanQ
But who knows. . .
Nice tidal video..!
