Friend went through the canal and had to sit for a few days with a bunch of other ships. That's something operators hate. Because any time spent waiting is lost opportunity. I'm assuming being able to punt and offload and swap cargo would be a welcome alternative for operators. Maybe you spend a day to offload and load new cargo but that would beat waiting two days for a slot to open up at the panama canal.
