Just be cautious, dry adapt won't give you legs. If you're washed ashore you'll have a long crawl back.
We Selkie reverse dry adapt to breathe water so as to stay deep as long as we like.

Adapting to the dry in this way requires a connection to one's ShifterSelf?, and not everyone has that. Those without can be trained to use a relic to focus or an air gill as a substitute, though it's not indefinite and loss of the item signals trouble.
