Interesting what’s happening around Iranian ports these days. Windward, the British maritime analytics company, has just documented how several vessels have already found ways to bypass the U.S.-imposed blockade.

On April 14th, an Iranian-flagged landing craft managed to depart from the Iranian port of Abbas, cross the Strait of Hormuz, and enter the Gulf of Oman. Clearly, it did not stop at the blockade. But what’s even more striking is another move: between April 14th and 15th, an empty supertanker sailed under a false flag in Iranian territorial waters and entered the Strait of Hormuz. According to analysts, it probably followed the coastline to reduce the risk of being detected. Windward also considers this a navigation that has bypassed the blockade.

The numbers from April 14th tell an interesting story. In the Iranian port and surrounding areas, traffic through the Strait of Hormuz remained quite active, although the flow shifted significantly toward exits. A total of 19 ships crossed the strait: only 5 entered while 14 exited. Among these, 7 flew the Iranian flag. The entries included two oil tankers and three cargo ships; the exits included two oil tankers, a bunker ship, and 11 other cargo ships.

What emerges from the report is that the American blockade is already influencing ship behaviors in real time, but it has not yet completely halted navigation. Strategies are adapting quickly, from false flags to coastal navigation. All this suggests that control of the strait remains fragile, and alternative routes are already becoming a reality at Iranian ports and in the surrounding waters.
