Fawcett's Bounty.
I actually considered this, I also thought it was quite reminiscent of the Goonies when you enter the cave and see the ship.
I also noticed a large “gate”, like the one at the entrance to the cave before the stone puzzle, only much larger. Maybe the water in the cave was much deeper at one point allowing the ship up to the gates height?
I have no idea but I remember a long time ago now the Dev who developed this puzzle said it was sort of a tribute to goonies. love that puzzle. no direct one eyed Willie but close enough.
Well, the pirate skeleton next to the end chest DOES have an eye patch…. My favorite puzzle also.
