To a limited extent, yes. But the moment you go ashore to re-provision, the 14 days start over at day one.
That said, a number of people with boats have quietly provisioned them, and plan to be living on the hook, well away from others, but not far from help if things go pear shaped. They think it is the best they can do.
Some people, who find themselves without jobs are going to live with loved ones in other states, while the states' boundaries are still open. I would expect a fairly total lock down soon, as we are on the front of the case expansion curve.
People are using internet
for contact with friends, as it is better than nothing. Some are picking up hobbies. It is up to us to entertain ourselves.
Some people are still doing the biochemical work
it will take to help more folks survive. Honestly, I think a quiet hats off! to them, and to all the emergency
services that are working, and to the people manning the grocery stores and their supply, is in order.
