Yes and no. Yes because you can't run a ship carrying some containers on a certain line as often, which means that the wait after missing a ship is likely going to be bigger. But also no because fundamentally the problem of having 10 delayed 2000 TEU ships is not that different from 1 ship of 20,000 TEU. Not to mention that ships only got about 2x bigger over the past 20 years, so the numbers I just pulled out of my ass are quite arbitrary. More smaller ships would give a bit more flexibility, but I don't think it's an easy fix for the current problems.
