I am trying to work out the time it would take for MTB 675 to travel 400 nautical miles on one or possibly two engines from the Norwegian coast - 30 miles west of Askvoll - to Dunbar, just south of Edinburgh. Obviously the weather conditions would have been a factor, but a general calculation would suffice.
My initial thoughts are that it would be around 40 hours if travelling at 10 knots, but not sure if that is accurate enough. One report gives 8 hours - 'Above Us the Waves' by Warren and Benson, but this seems a long way out. I would warmly welcome any guidance on this one.
Many thanks,
Bob
