This is good feedback on the stratechery article we're discussing here, which makes the 53-foot point. However, your quote seems to suggest they are _not_ currently used on ships? It says APL used 53-foot containers between 2007 and 2013, no? But sure, Amazon could be creating their own custom ship configurations, as the OP points out too, OP just said standard container ships and infrastructure for loading/unloading and dealing with them (and standardization is of course the point of containers) aren't set up to take 53-foot containers.
