If you struggle to park your car at the supermarket spare a thought for the person behind the wheel of this one.
In the latest look into our archives, we found these pictures of a cargo ship manoeuvring into Lynn docks in the 1970s.
The helmsman or woman has to inch their vessel through a gap barely wide enough to sail through at the top of the tide, when the River Ouse briefly stands still between the flood and ebb.
Today even larger ships sail in and out - usually without scratching their paintwork.
Trade at the port is booming, with a new bulk terminal and hi-tech crane the latest investment in Lynn's future.
But while time doesn't stand still on ther quayside, one thing hasn't changed - the skill required on the part of the crew to sail in and out of the docks.
