What exactly is the clearance on those cranes in Felixstowe?! It might be the viewing angle, but I could swear that Estelle is loaded higher than the cranes... On the Eleonora, we had to heel the ship away from the quay in order for the cranes to pass by in several ports in Europe (even with the boom up). The Chinese cranes had higher clearance, so the biggest problem there was making sure that containers weren't loaded too high for the destination port! Loading these ships have caused many chief mates quite a few gray hairs.
These ships might be very enjoyable to shipspot, but they are a royal pain to work on!
