I suspect that you'll use much less -- the shower head figures assume house
water pressures and boats are typically much less.

On Swee****er, between Panama and Papeete, with three people aboard (one
man, two women, no long hair) we averaged 15 gallons a day total
consumption, which included daily showers, drinking, cooking, etc. The
policy was, "use all the water you want, but don't waste it". And of course,
this was in the tropics -- you can get away with less in cool climates.

Make sure you install a shower head on the end of a hose so you can aim it
all over -- this helps to make up for the low pressure.

Hi,

Far Cove is set up for a shower, but was never installed. I was looking
at "low-flow" showerheads, and they say they use 2.5gpm. Egad - for a
5-min shower that's over 10 gallons! Far Cove has 50gal of water, and I'm
thinking of addding another 20gal tank, but still: 10 gals per shower??

Is this realistic? What is a practical estimate of how much water an
on-board shower will take?
