I think refueling a gasoline boat from plastic or metal jerry cans is a
dangerous practice and some marinas may even prohibit it.

Any gasoline transfer is suppose to have an anti static grounding system.
Not to mention safeguards regarding smoking, open flames, etc.

I see people refueling at the marina and public dock all the time without
regard to these basic precautions.

If I see this going on, I try to leave that area.

At least when you fuel at a marina fuel dock or the gas station, up the
road, they have grounded nozzles and the other precautions.

Another good reason to go with diesel fuel..
