Maany steel and aluminium boats might have built-in tanks - they are epoxy treated - maybe this epoxy can dissolve some of its chemicals into the water, wether this is RO, rain water or mains water.

I was on a boat last year with steel tanks - it had a of some kind filter under the sink and the crew drank the water - the chemical taste was very strong - it was RO water but it was undrinkable due to the chemical taste..

I don't now if epoxies eventually cures and doesn't give off chemicals or if the water approved epoxies were not used on this boat.

There are epoxy paints sold specifically for sealing potable water tanks. Some high build primers included. When I repaired our fibreglass tanks a few years back with vinyl ester, the tanks took a couple of months to clear the chemical tinge from the taste.
