Water storage.

Ditto, although I'd feel guilty about the amount of plastic waste

Just reuse them. I've been using the same dozen 2litre and 5litre bottles for about several years now. Fill those up with fresh drinking water at home, just use tanked water for washing and cleaning. Then you don't have to worry about filling the tank at start of a weekend away (boat lives on a swinging mooring, so that was always a faff).

As the title, what opinions are there for water storage onboard for a nominal 'month' of cruising, away from a certainty of marina's?
The caveat is of a small boat, in my case a Folkboat which already has an approx 40 litre aluminum tank, and sailing solo, no shower onboard.
The discussion with a mate is would it be better to put in a ''Plastimo' type flexi water tank", or to "have 50X2l water bottles"?
My view is the simple that I'll buy the bottles, which are refillable (to a point), less liable to contamination which could be catastrophic using the other method, don't require a working pump and are convenient. They'd be my 'consumption' supply of water, with the fitted tank being the washing/hygiene source for dhobi and body.
We're not talking RKJ stuff here, but a couple of old fart, preparing for a jaunt away on our own boat's from the Black Isle, up to and about the Faeroe Islands, without needing any water worries.

That’s a good trip in a small boat
 
One has to remember that the OP,s boat is a folkboat. Any additional weight affects balance & performance. Supplies for a month, along with crew's gear, can amount to quite a lot.
I would go for max 1 litre bottles, that can be stowed in various cubby holes. They can be moved to aid yachts balance & if one burst it is not the end of the world.There is less chance of spillage.
The main tank can be used for cooking, so it will be boiled prior to use. This will help reduce the chance of stomach upset. I accept that aquatabs can be used, but whilst I do use them they affect taste & I still get upset if the water is not properly boiled, when making coffee, or soup.
There is also the question of washing. 2 blokes on a small yacht for a month can begin to stink. They will need lots of wipes, plus some water for washing. Collecting rainwater from ( for instance), the boom would help. There are soaps for salt water, but the salt still has to be removed from the body - Or at least I would expect so. Having not tried it I do not know.
Others with experience may comment

Milady says the water from the tank doesn't taste as good as bottled water, so we have bottled water to drink. I think the bottled water tastes of plastic, but what do I know?

A couple of years ago we refurbished our water tank. It is grp and built into the boat. 800 litre capacity. We purchased a two pack polyurethane paint that is WRAS approved for coating potable water tanks. Water tastes great out of the tanks. We have a 1 micron filter in a 10" see through housing followed by a carbon block filter also in a see through housing. You can check to see the filter condition at a glance. No reason not to drink from the tank if its in good condition and fitted with a carbon filter

Oh all right
A 100l Plastimo type flex tank
Takes up as much or as little space as your needs demand - and easy to clean
Don’t forget the 2x 10l Jerry cans ( as much as one can easily comfortably carry ) to bring top up water aboard from that remote tap or highland spring ..

Where will the Op fit that in a folkboat?

Does the OP need a tank that big? 100 KG is more than the weight of an additional crew Whilst 2 L water per day is recommended ;so 30 * 2 * 2 crew = 120 litre; it is going to be a lot to carry. The Op has 40L tank so surely it would be better to balance that the other side of the boat (40 L tank, not 100 L ) Giving 80L storage . Then make the rest up with small bottles-- if he wants to put a lot of his water in a couple of tanks.

You’re missing the bit where I wrote ‘ take up as much or as little space as your demands require ‘
 
There are chemical additives to make water potable. Potassium iodide rings a bell... don't take my word for it though.

Even water collected from streams with yucky stuff in it can be converted into potable water ... but it will taste of a chemical... but who cares when when you need safe drinking water ?

Google will find the additives.

There are even special 'drinking straws' but they will simply have the chemicals in them that you can buy in bulk.

NOW if only there was a chemical that would turn salt water into distilled water...

I have yet to find a boat that carries a still and condenser to turn salt water into potable water.

Some people have made their own reverse osmosis or water makers ... or pay a few grand to buy one.
 
For clarity, my buddy and a I are both single handing our own boats in convoy if you like. It became a discussion, which will be continued tonight as I meet him for a few beers, and our wives go to a carol service together.
I'll report back, but at the moment I can't see anything wrong with the 2l bottles from Tesco, and refilling them when conveniently able to.
 
I use 5 Litre bottles bought as supermarket spring water and refilled from a mains water tap when the opportunity arises.
If treated with reasonable care the bottles survive a year. But I guess 2 litre bottles might be easier to store if wanted in large quantity.
