Thx Kort you are right.

The rear corner of the hull is the highest contrast area so probably will take precedence over the flags. Hopefully there will be some mist and poor light in winter to reduce the contrast more.
In truth I had hoped to blow out the background even more than I have done here.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
