I made the holding tank and ice box for my old 32' Traveler by first fabbing
a mock up with cardboard, (you can make a lot of adjustments/mistakes with
cardboard for free!)
Once I had the shape I wanted, I took the cardboard parts and used them for
patterns for 1/4 exterior fir plywood. I then laid 2 or three layers of fg
cloth/epoxy on the inside surfaces of the plywood pieces before assembly
with bronze ring nails. I then filleted (epoxy and low density filler) and
taped the fillets (cloth and epoxy). I installed deck plates on the holding
tank for clean out.
For the ice box, I placed a pan of boiling water inside and closed the lid
and left until the water cooled. As I remember this was to harden the epoxy
and keep odors down. Something like that anyway, sounded like a good idea
and I never noticed any (odors).
I got that from "This Old Boat" (I think) which is a great book for anyone
wanting to work on their own boat.

there are potable water approved epoxies. Approvals (NSF 61) are
generally for tanks 1000 gallons or larger

Yes you can make a F/G epoxy tank.

Make sure you finish the interior of the tank wity a couple of coats of
"tank resin" which is a resin approved for tank coatings.

Seal the lid to the tank with SikaFlex 291.

Good luck.
