(20 April) more than a dozen ships from the flotilla successfully diverted a vessel carrying raw materials destined for the Israeli arms industry

Specifically, the MSC Maya, a container ship belonging to the multinational shipping company MSC – Mediterranean Shipping Company – measuring nearly 400 meters

uhhhh then why is it at port?

Calling this a blockade is kinda stretching the definition of the word a lot, like they made the ship move a few meters to the side and called it a day.
