The old Panamax chips could only carry 5,000 TEU containers (20 fott containers)
Since the Chinese took over the canal, it's been expanded and Neo Panamax ships can carry 14,000 TEU. Maximum length for container ships went from about 950 feet to over 1200 feet. Width went up from about 106 feet to over 160 feet. NeoPanamax is longer but narrower than Chinamax.
So, will the container ships coming across the Pacific (or now in the L.A./L.B. harbor) be able to fit through the Panama canal?
Super containers are 24 TEU
