But a more reasonable option along that line of thinking would be to look towards layers - Light weight inner layers of tight weave fabrics to catch and hold skin oils can then reduce the frequency needed to wash heavier outer layers.
Asking "Does this really need to be cleaned now?" and "Can this be spot cleaned" can go a long way towards reducing over all water and energy usage whether on land or on a boat
. A brush can occasionally go a long way towards extending the clean-life of some garments between actual wet washings.
The biggest downside for a lot of water saving concepts for something like laundry is that they'll take time and energy, but also can end up taking a ton of space. So careful trade
offs have to be considered. Don't forget that one of the biggest efficiency factors in any system - volume - can mean you carry more clothing
and wash clothing
in larger/longer batches... But what are you doing with the soiled clothing while waiting to build up enough to justify a high efficient-high volume process? In a home that might not be a huge deal, but on a boat
that could mean lockers being over stuffed and encouraging less than desirable life-form growth.
If you have the space for it, you could consider running with 'saved water' stages while doing larger amounts of clothes at one time. Rather than discarding water after its first use it is instead reused for a later washing
This can be as simple as the rinse water from the first load becomes the wash water of the second load, or you can expand it with far more stages. Pre-wash, [multiple wash stages] [series of rinse stages] - The goal being that each litre of water used in a given stage is less likely to become contaminated to the point that it can't be reused at that stage, but is also reused in an earlier stage anyway after reaching 'exhaustion' on its current
For land based wash systems they can even go a step further with settling and separation tanks
to extend wash grey-water usage, but on a boat you'll be limited to trying filter setups - Unless you find yourself hopping between desert islands you can setup camp on without access to more fresh water?
