Instead of Luffy, you're the captain of the Strawhat Pirates, still with Luffy's power.
What would you have done differently?
For me, when going getting to the top of Reverse Mountain and just starting to go down again, I would've reached up at the rocks above, gotten a firm foothold wrapped around parts of the ship, and slingshotted the ship over the mountain, hopefully reaching "Raftel" on the other side (eventually maybe).
Luffy wouldn't do it the easy way. I would.
In fact, if I found that big golden "Ark", I would've settled for that instead of One Piece too. Who needs "pirate king" when you've got a giant hunk of gold already?
I am actually more interested in the hancock shower part but probably i would have been turned to stone in matter of one second so…
