Wow...engineless...How long ago did you do this? Where did you leave from?

Re: Water Usage

That trip was in my adventurist youth,mid 1970s. left from Mazatlan out to Socorro Island. just to see if we could find the Island with my plastic sextant, and newly learned skills. It all worked fine and after a week at Socorro, we left for the Marquesas, approx 2400 miles in 22 days. By the last week, I was feeling tired and came down with a nasal infection that I think came from dehydration. There were 3 doctors anchored in Atuana, and they fixed me up real quick. I think the fresh fruit and lots of water, and the sleep of the dead for a few nights did most of the curing. I was much more careful about hydration after that. Contessa,s Rock. _____Grant.

I'm not judging you - just as curious about your usage as I was Impi's.

Funny thing I was wondering the opposite...

"How could all these people ever consume that much water on a daily basis"

Even when I'm working out steadily it would be hard for me to consume more that 3 Times this number that I mentioned....

Quoted from a source....

"2 litres is a good minimum for the average person to drink in a day in order to maximise brain function, expel waste from the body, improve your mood, raise your energy levels and hydrate your body, skin and hair. At first you might find all the water consumption difficult to keep up, and even boring to remember, but if you stagger your water intake, in small amounts often rather than downing a litre at a time, you will stay better hydrated and avoid running to the toilet everytime you drink. "



I never once felt dehydrated, and know the symptoms...

Dehydration: Symptoms - MayoClinic.com

I was not trying to test myself or pushing myself to the limit, and my companion actually drank less water then me during periods....

You'd be surprise what you can get away with if you manage your energy.


Obviously your food has water in it as well, and I didn't calculate that if we ate an orange that was apart of our water....

Impressive in a 26ft, boat. I have to laugh because they are going at it again on another thread about charts vs. plotter. Then a guy like you with a plastic sextant and a few gallons of water goes to one of the most ideal places in the world...good job

Really, I'm not judging - just understanding the "low usage" side. Your one quart of water per person each day is very frugal, and less than that required as minimum in the sources you quoted in your reply.

We use 3-4 gallons each per day. I never thought this was a lot, but now think it is compared to many.

I easily drink a gallon each day. Yes, I could "manage" my hydration and spend a lot of time focused on my internals, but the fact of the matter is I drink as much as I want when I am thirsty, and I sweat like a pig in the heat. I know I lose a gallon of water in sweat each day - it runs off me in rivers.

So now I am down to 2-3 gallons after drinking one. I am in the water a lot and take a fresh water rinse when I get out each time. Keeping salt out of the boat is very important to us. Also, after spearfishing or diving off the dinghy, the dinghy gets a quick fresh water rinse. Again, keeping salt off the boat and our clothes is important to us. Then I take a shower each night.

Similar for Michele, but she doesn't drink as much because she is good in heat. However, there are dishes and laundry and her shower probably uses a bit more than mine because of hair.

But that is our requirement - no saltwater dishwashing or bathing and no focus on metering out water through a hole in a bottle cap or other such worries.

When it rains, we feel bad because we can catch 100 gal in one hour, after which we just watch the water fill the ocean. We can never use it fast enough during rainy periods.

Re: Water Usage

I think, as it has been pointed out, that the amounts of water listed as survival minimums dont take into acount the water that is contained in food. Canned peaches and fruit cocktail contained water and sugar, and augmented the low water intake. Even with that, I never let myself get dehydrated after that passage.. I also dont think I have ever opened a can of fruit cocktail since. Would I do a minimalist trip again?????. Hell yes, if the finances said minimalist or dont go. _____Grant.
