I have no idea how the mix you describe will hold up, but two things
you have neglected to consider in the above is that sunlight/ultra-violet
light exposure may rapidly degrade this mixture when used in to seal a
structure, where used in a boat it would typically receive very little
light exposure.  The other possibility of concern is that the solvents
in the mix may dissolve or seriously weaken the earth bags.
