Clothes? What clothes? Ha ha. What we do on our tiny
trimaran...
Wash in fresh. Minimal
water. Minimal soap. Agitate and scrub apenty. Rinse in
salt water till all the soap is gone. Rinse in fresh. Squeezing most of the
water out between steps is also important.
We have a water tank holds 40 gal max. Another 15 in jugs. We crossed from
panama to
marquesas 4000 miles nonstop. 25 days. That was our longest
passage to date. We washed clothes twice after rain showers. I guess what i am saying is you dont really need thousands of heavy gallons of water. Just be frugal and concious of water usage. If you dont have it to spare, dont wash the clothes.
