How about nylon webbing with rubber gasket material as chaffing and under

I just discovered that the poly holding tank in our boat is secured (or was
until the screws pulled out) with galvanized steel strapping. Gawd, the
former owner loved the stuff, it's even holding up the exhaust hose line.

Obviously, I've got to come up with something else. I can think of a
number of alternatives but, if anyone has done something they think worked
particularly well, I'd like to hear about it. I want to be able to get
the tank out easily and not risk abrading it if it shifts around with the
motion.

Actually I installed a poly water tank with galvanized
strapping. It wasn't ideal but didn't offend me too much.
Used neoprene padding under it at the corners.

Nylon webbing does sound good if you can come up with a good
tensioning device (multiple lashings through a sewn eye??)

Further to Evan's note:
Steel or aluminum strap, with a moulded rubber underbelt is a standard
aviation fitting. At the terminal ends, the strap is often folded
back round a steel dowel and riveted. The dowel has a transverse screw
hole which is revealed by a slot pierced in the strap.
Another style of terminal is made in this way: threaded rod is welded
to a plate, which is in turn riveted to the strap, each end.

Nylon's strength is gained from its extended strain capability (it is
"stretchy") so that heaving loads can shift and rub on their mounts
if secured with nylon strap.
A polyester or terylene strap, such as you find on your seat belts is
stiffer.

You can see the terylene strap to metal stitching very clearly on seat
belts.
They are rated (if I recall) at 30g which is rather more than any boat
structure can handle, typically.
