ONE wonders whether giant container box boats should be allowed along the Suez Canal when a gale force sidewind is blowing.

The area of ships’ hull, plus its container stacks, creates a huge sail.

In the open sea one can compensate for sideways drift, but not in a narrow channel.

I was astonished at the small crew – how do they manage to stay awake and operate these ships properly?
