A second shot at water

Water, we all need it!

Since my last post about water I have had some discussions with more experienced sailors on some of the different sailing and cruising forums. I realized that I was thinking about it all wrong.

I was thinking about how much water the two of us would need to survive, not how much we would require. One person asked if I was talking about potable water or water in general.

Although most people agreed on that my plan for the water tanks was inadequate, a select few said that it was very doable. If, one would use the water for cooking and drinking  only. The luxury of a shower was limited to a cold seawater shower at best. Most of the time wet-wipes were used. Don’t knock the freshening power of a wet-wipe and dishwashing sponge bath on a hot and sticky summer afternoon!

Anyway, I now have realized that a more overlaying plan is needed. And water conservation seems to be on everyone’s lips. Dual taps in the galley, one for freshwater and one for seawater, is almost a requirement rather than a bonus. People shared many conservation ideas, something that can be very important when the water supply is limited.

We plan on carrying a lot of water. One 40 liter tank. One 70 liter tank and one 200 liter waterbag. This should be enough for two people for about 30 days while crossing the atlantic. And with rationing, It could last much longer.

What about seawater? Isn’t there some kind of ratio that would be ok for the human body? Or how about using it for cooking?
One of the problems with seawater is that it has many different types of salt. Not just sodium chloride, which most of us know as tablesalt. In the ocean there are magnesium, sulfate, calcium, and potassium salts as well. Really not good for you.

So how much seawater can a person drink? None really. If you drink seawater and don’t have access to fresh water, you are allready dehydrating your body.
