Newbie-Drinking Water from Boat Tanks OK ?

Hello All!
Also new to cruising and need to know if water from water tanks on boat is drinkable or should bleach or some kind of "purifier tab" be added to water supply.
We're crusing the Abicos (4 people on 37Ft Beneteau) for 5 days and will overnight mostly in marinas.
Is hauling water better idea?
Many Thanks!
Sybil

It all depends on the quality of the water you put in the tanks. Put nasty water in, get nasty water out or vice versa.

I take it this is a charter? If its a charter, I wouldn't worry overly much. I am sure if its a reputable company the tanks are clean enough. If it is in fact your boat, there are several different filters available for the tap from inexpensive Britas to expensive Sea Gull systems.

It's a good question and one that makes me laugh in the "big" picture. My wife won't drink unpurified water now.
But, up until 100 years ago, we drank out of streams, lakes, water from rain gutters, and shallow hand wells. Our race did that for 100,000 years. Then, for 90 years, we drank water from deeper wells. Some times it was treated if delivered by a muni. Now, we have been convinced that to drink water thats not from a bottle will make us sick so we are spending more to purchase water put in a bottle then beer put in a bottle.
So, now she drinks bottled water and I drink beer

All boats are different, and it is relative to the maintenance and construction of the water system. "IF" I know the source of the water that is or has been in the tanks, I drink it as is; otherwise I boil or disinfect (bleach) the water THAT I ACTUALLY CONSUME. The rest goes untreated.

If you have a good nose, close your eyes and sniff it in a clean glass.
Next, compare it with a glass of known good water.
That will tell you a lot.

Living aboard for just 20 years now, we drink out of our tanks every day. As Mimsy said, be careful what you put in. We do filter everything that goes into the tank through a charcoal filter and we are careful where we fill up. Once a year we "shock" the tank with chlorine and flush the lines, but that is about it. We have filled the tanks in many third world country and to date, have never had a problem. Chuck

Water that is stagnant for long periods of time usually needs to be treated to eliminate bacteria which could give you Giardia or other bacteria which does not suit your intestinal system well. This has nothing to do with how good ones F/W system might be.

In very small quantities (4000:1 ratio), pure bleach (sodium hypochlorite) will not hurt you. It is nothing more than salt water with a much higher ratio of chlorine ions to sodium ions.

"Sodium hypochlorite has been used for the disinfection of drinking water. A concentration equivalent to about 1 liter of household bleach per 4000 liters of water is used."

I probably should have added that problems with water will be less if you are a live-aboard than they might be with an occasional user. Turning over the contents of the tanks helps in keeping everything clean and fresh. Tanks that sit empty for long periods of time, or worse yet, sit with water in them will develop smells and critters. That is why we use the water in our tanks and don't connect directly to the dockside water when we are in marinas. Chuck

If you filter the water going into the tanks, doesn't that take out the chlorine? I'd be wary about untreated water sitting for any length of time. We do filter, but then also have a filter on the tap.

Also, I think that world cruisers tend to build up their immunity systems because they are exposed to a lot of different germs than occasional sailors, for what it's worth.

That is some good advise, but be careful in adding bleach to the tanks that have been treated with other chemicals, including those treated from municipal water systems. And never leave water with bleach sitting in a stainless tank for a long time. It is OK to shock treat a stainless tank, but the tank should be flushed immediately after the shock treatment. Chuck

When water sits in a tank, it can smell like sulphur. But it is still fine. Run the water through a hose and back into the tank and it will smell fine, all it needs is aerating.

Sybil, Before you take on water anywhere in the Bahamas, be sure and taste it first and look for salt water. We contaminated our tanks at a marina in Nassau. We have been to marinas in other parts of the Bahamas where suddenly the water got very salty. Chuck
