Did that 20 or so years ago, except used 2" sheet eps home insulation
instead of a premade cooler. Made it custom to fit between the second and
third thwart on a 25' Old Town canoe. Not only will it hold food and beer
for 6 and keep it cold for 3 days, but also provides a quite comfy seat
for
that station on the boat. No carbon fiber, way too expensive back then.
Still in good service today.

The problem with the test as initially reported is that coolers do not stay
closed and are opened repeatedly during the course of a day on the water.
That alone is a variable that is not taken into account.

Regardless, I would just rely on what the manufacturers claim and leave it
at that. Life is too short to worry about one cooler keeping things colder
than another for a whole 3 hours, 25 minutes and 22 seconds. ;-)

Keep the cooler out of the sun and the top highly insulated brands will all
do equally well. For me it would be more of a matter of cost. Another
consideration is a 12v cooler. They work great if you have the battery
capacity.

Cooler Joke: A redhead girl was walking down the street. She was carrying
a boxy object suspended from a handle and ran into a blonde friend of hers
who never saw such an object.

The blonde asked what it was, to which the redhead friend replied: "It is a
cooler. It keeps hot things hot and cold things cold".

The blonde was impressed and immediately purchased one.

The next day the blonde was walking down the street with the cooler and ran
into one of her blonde friends.

Her friend asked what she was carrying as she had never seen such an object,
to which the blonde replied: "It is a cooler. It keeps hot things hot and
cold things cold".

The other blonde was impressed and asked what was inside, to which the
blonde replied: "A cup of coffee and a popsicle." :-)
