So, I guess if the OP was asking how to start an open fire on the deck, I should just tell him the two sticks method.
(tongue in cheek.)
Well you'd have to assume he's already got a way to contain the fire, right? What if he just landed a whale and needs to render some blubber? I don't think the two sticks method would work if there was much wind. Here's a tip: The best way to start a fire on deck is with your expired flares! If you happen to run out of flares, DON'T PANIC, your deck fire will make a suitable distress signal.
