Occams Razor would suggest that they may not have caught the virus on the boat then but perhaps after, no?

Why? 23 days for the longest time to succumb isn't surprisingly long. small exposure, healthy person / lucky genes, good medical treatment, but not quite healthy/lucky/good enough.

Well the longest possible according to this data would be 54 days. We don't know the identity of patients who died, could be one of the people who tested positive on Feb 1 (or sometime in early Feb).

Given current information, Occam's razor cuts the other way. Unless perhaps that person had another known significant contact.
