We spent much of today motoring through the Kiel canal. It is 66 km from Rendsburg where we spent last night to the locks at Brunsbüttel on the river Elbe. For much of the time the canal runs through flat countryside but this is difficult to see as the canal is lined with mature trees that are probably as old as the canal.
The bridges over the canal all have a clearance of 40m so can allow quite large ships to pass. The two bridges pictured are obviously old but are in regular use. The plates are riveted together rather than being welded: perhaps they are part of the engineering masterpiece that so impressed people when the canal was opened in 1895.
We didn't stay in Brunsbüttel, but locked straight out into the Elbe at about 6pm. There was a fair tide running down to Cuxhaven. Elbe tides are fairly formidable and can sweep past the narrow entrance to the yacht harbour at 4 knots or more. Getting into the harbour with this sort of cross-current provides a great deal of excitement and a profound sense of relief once in port.
So Bonita is once again floating in tidal salty waters. No doubt this has provided an unpleasant shock to any fresh water marine life that may have taken up residence during our time in the Baltic. We also have to unearth the tide tables and plan our sailing around times of high and low water again.
