Chapter One
The Shape of the Passage
Imagine standing on the bridge of a cargo ship before sunrise. You can see a strip of dark water ahead and shore on both sides. The ship is going somewhere far from this coast, but for the next part of the voyage its world has contracted. Its captain thinks about traffic, visibility, machinery and the passage ahead. The people who will eventually buy its cargo may never hear the name Hormuz.
That imagined bridge is where this book begins. The Strait of Hormuz is a connection, not a destination. It links the Persian Gulf to the Gulf of Oman and then the Arabian Sea. Iran faces it from the north and Oman from the south. A map can make this look effortless: an open blue shape pinched at one edge. From the deck of a vessel, the same shape means limited room, neighbouring jurisdictions and a great deal of other traffic. Geography becomes a series of human decisions.
The first decision is whether the voyage is possible at all. An exporter inside the Gulf can move a barrel of oil by pipeline if it has access to a suitable line and terminal. It can store some barrels while it waits. It can sometimes sell to a nearby buyer. But a ship departing a Gulf port for the open ocean must pass through the available sea exit. There is no second mouth on the opposite shore waiting to be used. That simple fact gives a relatively small waterway a very large economic role.
