C27 Where Is This?

Riester and Rhett were happily floating in their diary...

On the first day, after a storm, they lost the mast, but fortunately the mainmast.

The next day, Rhett fished a lot of fish and began to use pure sea salt to marinate the alkaline fish. Riester was sleeping...

On the third day, the alkaline fish stank and the marinating method failed. Rhett continued fishing while Riester slept..
