Not worried about the pandemic getting bad I have reserves of water and food for some months problem is people loosing jobs and acting a fool when resources get low. In America we have 3 guns per citizen when all those people start getting desperate it can be a recipe for disaster.If that's the standard, which exceeds conditions ashore, I get it. That would need to be one serious destruction of society. These pandemics are very unlikely to rise to that level. You can avoid infection, by simply not coming in contact with other people. That can be done ashore, as easily as at sea, and retain refrigeration and fresh water. All you need to do is stock up the chow.
I just realized how many people I know who are dependent on pharmaceuticals. One is thyroid replacement, others are cardiac disease, etc. Some are depression meds. None of these folks are going to survive offshore for long.
