How to use Egyptian Pontoon Ferrys?

[Boisforas]

Hello Eric,

As a narrow waterway the Suez Canal does not allow for shallow water for loading and unloading, there are Marsh hexes for that purpose. Both pontoon ferries and units can enter / exit Marshes.

Hello Kat,
  But how do those ferries work? I can move them up & down the canal but how do I make thejm ready for troops to move on & off them/ Do I have to move them to a marsh hex/ Eric
