Second Biggest Natural Harbour in the World

There are a couple of posters in the lounge who would benefit from being sent out with a tape measure, without limit of time, to go round all these places and report back at some point in the future once they have found the answer. And not before.

Poole had a 100 mile coastline before fractals were common knowledge. I believe it was measured by a man with a 12 inch ruler and muddy knees. As I said, life was much simpler then.

I'd be worried that he might have lost count during the 528,000 times he would have had to turn the ruler over. No, hang on, he would only have had to turn the ruler over 527,999 times ...

I'm sure that some measurement error must have crept in, but the answer was definitely 100miles.

So. What is a natural harbour? An expanse of sea separated from the rest of the sea by a narrow entrance, thus providing shelter? OK, but how big can the expanse of sea inside th harbour be before it is too large to offer shelter. I wouldnt exactly call the whole of SF Bay - or even Falmouth - a harbour provinding shelter to anything but the largest craft. there are lots of places within those 'natural harbours' where my 36 ft yacht wold find shelter - but most of it, in a blow, would be scarey

If its only the enclosed space with narrow entrance definition, I guess the whole of the Med counts as the biggest natural harbour.
