I just realized that there is a passenger ferry service from Kuwait to Iran, and even a Ro-Ro line so you can take your car with you. Reading about the requirements it doesn't seem to be such an impossible mission.
Has anyone ever used it? If so, can you share any tips? If not, wish me luck, I will share them with you if I survive to tell the story.
