Much further than that. At least 200nm using drone ISR to cue Shaheeds, 500nm with satellite ISR. (With a 90kg warhead.) There are also many fishing vessels in the region, originating from a number of countries (e.g. Oman, Iran, Pakistan) which can report sightings of VLCCs.
Once you have sighted the ship it is an undergrad project to implement target classification and recognition using off the shelf algorithms. It doesn't need a fast GPU because naval engagements are very slow, a cheap mobile phone can do it.
How many innocent fishermen are you willing to murder? And of course, the famine in Balochistan that would follow. Maybe not a great idea if you want an uprising of the Balochi against the Persians.
Oman is a regional ally, but they would not stand idly by while their citizens are killed.
Practically speaking, the Musandam Peninsula [1]. Open that to the sea and you make everyone except Iraq and Kuwait happy.
