On the 54, rainwater that hits the forward port 25% of the boat drains out one pipe on the port side amidships. 

We stuck a big bucket there during a big rainstorm and kept measuring TDS until it got down to 4PPM (!!!) and then had a pump with a long hose+prefilter push the water through my normal "shore water" filter system which includes a 5micron filter and then a 0.5 micron carbon block filter. Then anything we drink goes through the Seagull filter.

I think I put 700 liters into the tank in less than an hour. 

Now that we've polished the stainless for the first time in years, don't think I will putting the water into the boat's tank, but rather just keep it for washing diving/fishing/kitesurfing gear. TDS won't detect chemicals, FYI.

Hi again Nicolas, one more comment. I never use the watermaker in harbours (unless large and clean) or marinas for good reason and if I spend a week or two in that situation rain collection is a big help.

Hi Nicolas, glad to help. I made a rain catcher tarpaulin with a shape to the center and a funnel shape to attach a hose to and ran the hose to the tank filler. I tied it to the shrouds. In the tropics you get intense showers of rain and you get a lot of water in a very short time. I have also tried a variety of ways to catch the water coming off the full cockpit cover we have and off the mizzen boom tent we set up to give us shade as we lounge back on the deck mattress we have on the rear cabin top.
Kind Regards

Hi Nicolas, At times I collect rain water direct to the tank and it is drinkable as it arrives. The water for my land based living for the past 22 years has all been rainwater collected from the roof of my house and we use it as is, no treatment, no filtration, no issues. We do live in a small coastal village of around 2000 so air pollution is not an issue. No doubt at times a few bird droppings must be on the roof but still no issues.
Kind Regards

Hi everybody 
i would like to use this subject of filtering water to ask if some of you collect rain water ?
if you do , do you store it directly in the main tank and in that case how do you render it drinkable? 

thanks for your input, kindest regards 
and fair winds

That's more about experience sharing. I'm very happy to listen experiences other than mine. Yours is also interesting and not "have to" to anyone as mine. Thank you for sharing. 
I was also very happy to read about Seagull system, that looks better than RO I use. That's the value of sharing. 
Water tank treatment depends from situations and sail style. 
Cruisers, who run watermaker daily, living on board 365 days a year have constant water tank flow, therefore less risk. 
Comuter cruisers like me, leave boat for few moths and have issues with tank cleaning. Marinas water have various issues. Even in Med. France generally very good, Italy, Greece varies a lot especially islands, especially this summer. Not mention pacific, where generally much safer to rely on watermaker.

This is fine to do if you WANT to, but nobody should feel you HAVE to.  

I have been drinking water straight out of boat water tanks for the 20 plus years I have lived on aboard boats. Straight up, nothing but a coarse mechanical filter. We don't ever carry bottled water. We carry a jerry jug--that we fill from our tank--of water for a mid ocean passage emergency.

Domestic reverse osmosis filter for tank water
 
Still my best investment in terms of ROI. Reverse osmosis filter. Have one at home, so I know it's simple and reliable. Was surprised to find it in the bigger 80' sailing yacht. Captain was happy for a few years and I have heard his arguments.
No , it's not hydrophor for the watermater production as it is installed in some newer Amels.
It's for water filtering from the usual water  tank. And you know, it's never clean in real life.
Installed it this spring and can confirm the arguments of another captain.
- reduce to minimum shopping heavy plastic bottles
- feel good for less plastic pollution
-drinking water is not limited by capacity for hydrophore - it constantly refreshes from the water tank, not needed to run watermater.
Some bottles still remain for safety,
price ~ 200 Eur. Including 24V motor for pressure and 5ltr hydrophore.
There are a lot of suitable brands - I even don't know mine.
Best pace I find - lowest bilge under the sink. fits well, including a hydrophore tank.
 
Now we sail in Med. In case we'll sail pacific probably i choose the system that collects water from the watermater, because i neeed to run in it daily.
