A friend was a Blue Funnel officer. He said the East Float was big, but the big King George V Dock in London, built in the 20s were bigger. I disagreed as I have been to both. The London docks were a white elephant as big ships could not sail up the Thames.

The KGV don't look that big:


The East Float is impressive and I always thought bigger than Gladstone. But Seaforth is bigger, as it was the largest docks in the country when opening in 1972, with the largest dock gates too.



Gladstone may have more water space between the branches overall, and more quay length, but the East Float is one large impressive expanse of water at its widest.
