Search HUBB for "egypt ferry" and "egypt ferries" and you should find the relevant info.
To the best of my knowledge these services are suspended. The only one still running is a freight ferry, which also takes passengers. But, there are some strange restrictions on where passengers or vehicles can get on or off, and in Egypt passengers can't get off!
I think the service to Haifa is still running, but it's no good if you want to leave the area via Syria, because you will be denied entry if you have passed thru Israel. Just like the Middle Ages!
Good luck! If you find a ferry make sure to let Grant know for the Shipping Pages.
