VERY nostalgic. From late 1978 to mid 1980 I must have done that trip aboard the Norland or Norstar a hundred times, back and forward to Holland.
A superb service it was too, and all the food you could eat was included in the ticket!
The vid didn't show the incredibly tight clearance between the ship's side and the lock out to the Humber. There was maybe 6" to spare on each side!
