i have to correct my post about the daredevil Alain Bombard surviving 1 month by drinking salt water..it was 1 week! for sure....more precise 10days drinking sea water only; and 4 days drinking fluids from the "seafood" he catched..(total 14 days without using "water reserves" (also not collecting dew)!
(as usual wikipedia gives only vague information about what/how he really did it.)

this is a golden rule that comes from the experiment: do not drink more than 800ml sea water per day..only taking small sips! keeping your throat from drying out is vital for keeping "the spirit"..(the normal healthy kidneys can handle 800ml saltwater per day for one week and then you need to give the kidneys time to get rid of the salt for a while) drinking salt water buys you the time to find other ways to get to "water". (most living creatures of the oceans have some fluid good for drinking. the poisonous ones are more in coastal regions)
...and..having a sponge is of great help for collecting dew..and lots of plastic/foil or a sail can help collecting dew...but sometimes you just don`t have the luxury of being prepared or lose the equipment in a "storm".

so one week salt water drinking won`t kill (max 800ml per day!!! taking very small sips!!) this will provide time to catch whatever you can and thereby slowly improve your means..

it is highly advisable to read the book

number one killer is panic (OMG no food no water!)
