Well...if someplace wants to be picky about filling your bottle...
you could keep one of these around and with a few other hardware store sourced adapter fittings...you could put a deposit down and buy a couple of their full bottles, take em' to your boat, fill your own, then turn the empties back in (and hopefully get your deposit back
) If you don't get your deposit back...at least you got your propane...and a couple extra boat anchors...(or maybe a local would buy the empties off ya)
