A very good sailor once told this to me as we sailed past two yacht, one French and one Dutch, on his yacht,
The Dutch were better sailors than the French, or at least their flag designers were.
How is that I asked.
Well if you look at both flags and think of both of them after they have aged quite a bit, the ends will become damaged due to flogging in the breeze. Despite this even if a third or more of the flag is gone you will still be able to recognise the Dutch flag, unlike the French one, because with a third or gone it will be a Blue and White one or just a blue one. .
