Here's a couple of my travel principles;
The less clothes u wear, the less that you (or Joy) have to wash.
The longer u leave the washing
, the more likely u will run out of clothing
on the day you are too stuffed to do washing.
The easier the system to wash, the more likely u will do it regularly.
A good soak reduces scrubbing.
The more the soap the more the rinsing.
The more the washing the harder to move around on the boat without bumping hanging washing.
So, before too much washing builds up, I use a bucket or basin (which are multi-purpose so are space effecient), soak clothes in water
and minimal soap stuff, rub dirty areas together by hand (I wear washing-up gloves), slosh around, wring, rinse using a small amount of water, then do the wring and rinse a couple more times until rinse is clean, hang 'em up using pegs which stop 'em from flying over the side with unexpected gusts.
One place I was at, on wash day, I would row to the public wharf and collect several buckets of water. Since the piping out to the wharf was black poly and in the sun, the water came out very hot. Nice for washing clothing
[Edit: Oh, I discovered that red dirt on white clothing is extremely hard to hand scrub off so I reduce my washing effort by having clothing of a colour which hides dirt. And I also stopped rolling around on shore where there is red dirt.]
