This problem is age old. Now the builders of new sailboats are locating the
potable water intake on the deck close to the bow of the boat.
This way it may not be fool proof but close to sailor proof. Color coding
is a good idea. Normally light blue for potable water, yellow for diesel
and red for gasoline. This way it will match the color coding used on
plastic containers.

Because I am such a dumbass that I don't learn from my mistakes,
Rosalie. Huh .. Through the years you've never passed up on a dig.
ThankYou to all who responded.

Rosalie, You might want to consider walking the plank if you're ever on
my sloop!
