Still, why were they in Iranian waters ...

I DOUBT they actually crossed into Iranian waters. Period.

Not the right question:

WHERE were they actually at?
WHERE were they actually at when the Iranians detected them?
WHERE were they actually at when the Iranians began tracking them?
WHERE were they actually at when the Iranians deployed their small boat squadron, and began trailing them?
WHERE were they actually at when the USN riverine squadron detected the Iranians and began tracking the Iranians?
WHERE were they actually at when the USN commanders off scene detected the Iranians and began tracking the Iranians?
WHERE were they actually at when the Iranian small boat squadron began close attacks (using radios to threaten the US riverine assault boats, began to use speakers, got close enough to shoot at (and for the US to begin shoot back)?
WHERE were they actually at when the Iranians boarded the US riverine boats?

Where were the US aircraft or helicopters?
Where were the US command ships?
