Compressed gas identification

Can someone help me figure out what kind of compressed gas is in this cylinder? There are no markings or stickers that would make it easy. I called some gas supply stores and they told me anything from nitrogen to chlorine to sulphur dioxide. This is what is known so far:
>Cylinder is 1 year old and never used, cylinder is from 10/15 and valve is from 8/15
>Low pressure cylinder with welded seam
>rotarex cga 660 valve (pictured)
>Colorless, odorless, tasteless
>extinguishs a flame (spray in plastic bottle and insert lit bbq lighter)
>appears to be lighter than air (if you wait to insert the lighter it will not extinguish and you cannot "pour" the gas onto a flame as with co2)
>no liquid in cylinder when shaken
>no spray or fog when either valve is opened
>does not super cool or freeze (I can put my hand right over the open nozzle with no immediate discomfort)
>Comes from a place that regularly uses and orders nitrogen, co2, argon, acetylene, and oxygen
Additionally this is what is stamped around the shoulder:
>Tw- 21.5 lb
>6848jj (likely serial number)

I finally bought myself a boat similar to the one above. It's an old Whaler, but modernized with features like internet, televisions, livingroom etc. Its about 44 meters long, and the engines are in top shape.
So, now I'm playing with the thought of making money with it.
My idea so far is to arrange some sort of expedition where each partisipant will pay x money for y distance traveled/diesel. Food/beer etc included in the price.
what do you think? any suggestions on how i should run things?
its a sea full of options!
