Seems to me the cruise industry is understandably desperate to survive. Desperate people can do desperate things. I`m wary of the industry, wary of what it might do, and as things stand wary of cruising again. I would not presume it`s survival, nor presume it`s demise.
The Covid issue affects cargo ships. Several times ships have arrived here with Covid onboard, necessitating provision of treatment, and ship quarantine. We do what we can and the ships leave. some ships, and crews, are in a parlous state. It`s a greater problem to confront elsewhere, where there are less facilities in less developed countries, eg in the Pacific.
