Some years ago, a client invited me to go fishing on a Buddy Davis moored in Pinas Bay, Panama, which is close to the Colombian border and out in the middle of nowhere. We flew in and were dugout-canoed to our boat, then later that afternoon motored on over to the "Madam" ( "Madam" & "The Hooker" were a large supply vessel--the mothership-- and G&S 50' sportfish, respectively). My guy knew the owner or captain, evidently, and we took on quite a load of fuel with equipment looking like it was from your local fuel dock: no drama.
Codger, I don't know what boat you were planning on doing this with---bunkering offshore---but I believe with a bit of planning in advance with someone you know who has a 'large' ( bigger than yours

) yacht equipped with a fuel transfer pump & typical nozzle, why not.
Of course, anyone who has had to transfer fuel from a bladder or apple juice drum to their own deck-fill in anything less than 'millpond' conditions knows this to generally be a fairly nasty job.
