I’ve been toying with the idea of making water tanks for my boat but
was dubious about using epoxy as a lining. I didn’t think it would be
safe enough for drinking water.

Like I said: epoxy paint for water tanks. Special stuff that doesn't contain
any solvents.
For instance SikaGard, a High Build epoxy coating. This system is a
two-component solvent free, high build coloured epoxy resin coating with
high chemical resistance, and approved for use in contact with
potable(Drinking) water.

drinking water approvals - called NSF61 - are generally tested
only on tanks over 1000 gallons. So, if your tanks are under 1000
you probably cannot find an NSF61 approved, potable water epoxy.
