There's almost too much to unpack here but this is the pic for an uphaul.
Listed under kiteboards, it shows a guy wrestling a sail (like it's an alligator determined to eat him) while in a motorboat, on a beach, by a calm sea. All this to sell an uphaul?
Edit: added actual pic so you can enjoy the greater detail of whatever is actually pictured

Where do I get a mast base that attaches to a gas can like that?
Euro pin gas can or US base?
