While anchored in Great Harbor Cay, Bahamas, we noticed something a bit unusual being done on a catamaran. Usually, cruisers will do their laundry and then hang them up to dry on the lifelines. This cruiser put their laundry up during a rain storm and let them get thoroughly soaked in the rain!
At first, my mind interpreted this as "they forgot to take their laundry in before the rains came" but they intentionally put them out as the rains were coming and even into the rain itself! They wanted their clothes to get soaked!
It took me a moment to capture what was really going on here: they were rinsing their clothes with fresh water.
On a cruising boat, clothes will get salty, no matter how hard you try to keep them salt free. Either a rogue wave, spray, or simply handling a wet line; salt will find its way into your clothes. Rinsing the salt out can consume a lot of water, and rain will provide you with such a resource.
After a long rain, all the salt will be rinsed from your clothes and you will have clean laundry. Once the rain finishes, simply let it hang out a bit longer to dry and you will have clean and dry laundry!
Next time you see rain coming, consider doing your wash cycles and then hang the laundry out for the rinse and dry cycles. It will save you a lot of water and time!
