Yosemite Sam continues using his pig-headed antics in a rather extreme way here compared to some of his other shorts. For example, not knowing that him and Bugs are the only crew on the ship and thinking that gold is buried under his own boat? But this is all in good fun! The show begins revealing Sam as a brutally evil character, as one of his crewmen manages to escape, but is now quite insane. By the way, Gravel Gertie was an old Dick Tracy character who had a treasure map tattooed on her head. A rather ugly character, quite fitting that they used this as an example as Bugs writes on the deck. And who cares how Bugs and Sam were able to make it back on shore themselves after the boat sank a few times?
