It is recommended that none of your passengers stay on the vessel during refueling. You should turn off the engines but you should also not turn off or on any electronic loads while refueling. You should also touch the gas nozzle to the metal of the fill fitting prior to squeezing the lever in order to discharge ant static electricity.I agree with Sardinia. Typical precautions should be used as in filling your vehicle at gas stations. Turn off engine or engines, no smoking, etc.. Maybe turn off batteries to completely eliminate the chance of sparks. If it makes you feel safer, by all means do it.
Gasoline vapours will not flow on deck to the wall mounted opening and leak then inside the bilge as the door is vertical and gasoline vapours on deck are extremely uncommon as breeze would blow them away and there should be no vapours ending on deck, except fuel is discharged in rod holder and drains on deck..I respectfully disagree with this. Gasoline vapors are heavier than air and will "sink" to to the lowest level.
Oh, i had first time covid in August but smelling was not affected, but i appreciate that you see also the positive side of it, and this is not only public bathrooms.I got COVID at Thanksgiving. I was not thankful. Additionally I can't smell a damn thing still. What should I do?
On the flip side, public bathrooms seem so much more pleasant.
