Use the thickest wall tank you can find, this can delay the odor seeping

That's because the source of your odor inside the boat had nothing to do
with the tank...most likely your hoses permeated with odor. Or, you
needed to clean your bilge--really CLEAN it, not just dump in more bilge
cleaner and/or bleach, followed by flushing out all the dirty water.
Dirty sumps are another source of odor that can make a boat smell like a
swamp, or even a sewer, because they generate the same gasses as a sewer.
