Frank Reed you wrote: “In Hart's "Romance of Yachting" there's a peculiar table for range of visibility. See below (attached). How many problems can you find with this table?”
Yes, there must be several problems. I can see at least three after a quick look. Therefore, as a bonus, who can ‘back engineer’ the table to calculate how Hart worked out his values (except in a dream)? Lateral thinking hint: Bomber Command Navigators didn’t change from using MPH to knots until 1st April 1945*. Yes, really; why on Earth didn’t they wait at least until VE Day 8th May. DaveP
