Sea water
Don't drink the ocean
Short answer
Salt is not a well. Swimming is a different page. Thirst plus pride is a highlight.
Also: ocean · salt water
How it works
The ocean does not hydrate you like a pump. This page will not invent a sip chart.
What to do
Find a well. Boats exist so you stop treating the coast as a pool.
Don't
Don't drink it as a bit.
