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.
