The secret for us for non drinking water usage was to employ a new bug
sprayer for both washing up and showering.
Shower on less than a gallon, wash dishes in like fashion.

These are the numbers I used for planning a transatlantic crossing,
mildly adjusted based on experience.
Note that if you cook differently you may use more water. My numbers
only account for water, and not for liquids in cans or within food
itself.
I didn't think of it in time, but you might consider using bottles of
water as you cook normally for several days to get a handle on how
much water you use cooking, and more importantly cleaning up.
Individuals also drink different amounts of water. If I drank as much
as the average below I'd drown. <grin> On the other hand, one crew
that was with us for two legs drank 3 l or more per day, mostly as
coffee.
Hygiene provides for brushing teeth, hands, and face and perhaps a
sponge bath. More on showers below. One of my crew suggested baby
wipes. Those turned out to be a boon to conserving water and making
everyone feel clean.
My crossing was an early Spring voyage on the Northern route. If you
are voyaging in warmer temperatures both consumption and hygiene needs
may increase.
Water consumption for washing up dishes varied wildly from person to
person. Even with sea water wash and fresh rinse, some of us (ahem,
me) used a lot of water to clean up while others could get the dishes
cleaned as well or better on half or less. You should test yourself
and your crew to see what is required.
- consumption 1.5 l/day/person
- cooking 0.5 l/day
- cleaning 4.0 l/day
- hygiene 0.625 l/day/person
That means about 2-1/4 gallons per day for a crew of two or 3-1/2
gallons per day for a crew of four. This is consistent with the
conventional guidance of about 1 gallong per person per day from
sources like the Hiscocks, Pardeys, and Don Street.
How you carry that depends on tankage. I had enough tankage to carry
water for the longest leg including a weeks margin. I also carried a
week of water in 1 and in 1/2 liter bottles.
Showers: I was amazed at how much water a shower requires. Friends
have a water flow meter on their boat and I found that even what
seemed a very careful shower took 3 gallons. Testing found that
washing hair over a sink takes at least 1 gallon for shoulder length
hair. Some of us could go a whole leg without a real shower (just
using baby wipes and a sponge or rag). One could not go more than a
day without washing her hair. People will be unhappy if they aren't
able to operate in their comfort zone. You are better off accounting
for the requirements and making sure that everyone has what they need.
In my case there was a good bit of discontent because most of the crew
cut back themselves when they saw how much water was being consumed
but then felt unappreciated by the high consumer.
Long answer to a short question. Do you want to know how to build a
watch next? <grin>
