You do not need a watermaker.
When I crossed the atlantic (not ARC) we were 4 men
aboard. I planned on 2 litres per day each, bottled drinking water
. Then all the tankage could be used for washing
I was surprised to find that the others (including the owner/captain) expected to shower
at least every other day. While I just let my facial hair grow, they each wet shaved almost every day. On the other hand, they drank only beer
, wine and hard liquor. They almost never drank any of the bottled drinking water. So much so, that when the tanks ran dry, they poured the bottled water into the tanks so that they could continue to shower
. It was at this point I started hiding bottles of drinking water from them. With 600 miles remaining, we first ran out of beer
, then wine, and finally cigarettes. As you can imagine, the other 3 crew become quite irritable. As soon as Antigua
was within range of our remaining fuel
(a question I was asked 4 times every hour), the engine
went on and stayed on, regardless of the wind
. The crossing was 20 days from Las Palmas
, Gran Canaria.
So my point, lost
someplace in my long, sad story, is to consider more than just gallons. Consider how the water will be used, what else you will drink, and how much washing
you will each do. Best to discuss with all the crew.
FWIW, IMHO a saltwater deck
bath is sufficient, with one bottle of water as a rinse. Fresh water is for drinking. And IMHO, alcohol has no place on a passage
. I'm sure there will be a bar within 50 feet of wherever you end up in the Caribbean
