Harwich harbour is on the estuaries of the River Stour and River Orwell and was for a long time the only safe anchorage between the River Thames and the Humber. The harbour has twin towns at its entrance: Felixstowe on the north and Harwich on the south side. Shotley is a smaller third town on the point where the harbour divides into the two rivers, and there is a Royal Navy station here.
"Harwich" is pronounced by the locals to rhyme with "marriage".

Arthur Ransome used the actual Harwich harbour with little or no fictional embellishment.
