Water Consumption

[masalai]

Dear Jack Daniels, last time I looked "ICE" is made of frozen water? - - - - - but then there is the addictive crystal called same - not to be recommended as a dilutant for JD or any alcoholic beverages.

but, in all seriousness... a gallon and a half to two gallons ration daily is appropriate. it's a very rough day indeed if you use it, and if you don't, just hold the ration over.

what's your capacity, and how many people? that's half the equation. the other half is conditions. humidity, temperature, sailing conditions(rougher sail tends to make for thirstier sail), how much work you expect.

and remember to carry about a gallon of rum for every ten to twenty gallons of water, if you can. never hurts.

If you look back at Mat-C's post (#5) you will see that we're looking at a 30ft planing powerboat. I would consider a watermaker to be an unnecessary complication on a boat like this. 4 people for a weeks cruising should happily get by with under 300 litres of water, so long as they're sensible. In one of my previous boats, of a similar size, the tank was only 90 litres. We used to manage for almost a week on that with 2 aboard.
A planing boat of this nature is unlikely to be underway for more than an hour or 2 at a time, so the only way you could produce enough water via a watermaker is if you had a genset &/or a decent bank of batteries - both of which would offset any weight gain you had by carrying less water.

The whiskey, however, I whole-heartedly agree with!

but what about the rum?

just no respect for nautical traditions, anyways.

hm. four people, seven days, 300 liters? wow, that's luxury. a hair over ten liters a day... no problem there!


hm. 30 ft boat, you should be able to fit a 50-ish gallon tank in no problem. you'd be looking at about two gallons a day, per person. a hundred gallons might be doable too, but i dunno about matching consumption with a watermaker, unless you go with a tiny tank and a large watermaker(not worth it then.), and get a solar still or two to put above decks.

The question has nothing to do with consumption per person.It is about how frequently you can fill your tanks. If you are going to cruise with stopovers every day, where water is available at the end of a hose, you need not carry large amounts. If you are going to cruise for days on end where filling is not easy or simply not there, than it is another question.
As far as i am concerned drinking water in 5lt bottles should always be there, no matter how big your tanks are or how clean they are. There is always a risk of contamination.

good point. still, sufficient water should be carried for a week. you never know when you're going to run into trouble and be adrift.

BUT when you run into trouble , you can knock off the theraputic showers , wash dishes with sea water and...
