In recent news reports that all seem to be saying the same things:
- Jakarta Post Indonesian teenager survives 49 days adrift in Guam waters
- NPR: 19-Year-Old Survives 49 Days At Sea After Floating Hut Drifts To Guam
- The Guardian Indonesian teenager survives 49 days adrift at sea in fishing hut
The teenager only had a few days worth of supplies and survived by catching fish, burning wood from his hut to cook them, and sipping seawater through his clothes to minimize his salt intake. (emphasis added)
Other reports mention running out of cooking gas for a small stove, and a week's supply of water.
Question: Is there any known technique to survive by drinking sea water for many weeks "desalinated" using clothing?
I can imagine using wet clothing as a cooling mechanism for use in a solar still, but I'd never heard of using clothing as a filter. I'm thinking that the early reports have been substantially mis-translated.
This answer make it clear that you'd have to dramatically reduce the salt content of sea water to get any kind of hydration benefit.

Salt dissolves in water so will pass though a normal filter or cloth. You can try that with a coffee filter at home. So there's definitely an error in the article.
A still is the only easily improvised way to desalinate water, but the article I read said he caught and ate fish - that will provide some water, and if there was any rain to catch even some of the time that would be a huge help. He presumably had some water with him at the start as well.
I suspect that, as has often happened before, the article said something like "survived by drinking seawater" when it should have said "survived despite drinking seawater".
