I enjoyed this cartoon for what it is worth, as I do most of the cartoons of this era I watch. Here we have the second appearance of Betty Boop, released less than a month after her first cartoon, "Dizzy Dishes". In that and this cartoon, she is a dog (as one can tell from the dog ears). Here, she is not the main character, but she appears enough to glean more of her personality than "Dizzy Dishes". We have here the first appearance of Bimbo, who calls himself "Barnacle Bill", in this episode. He is an annoying character in the way that he is very arrogant.
The episode starts in a cartoony way (normal for the time), where the crew are singing about being on the sea. The ship briefly docks and the captain calls all the crew (one of them looking suspiciously like Mickey Mouse) and tells them that they cannot leave the ship. Barnacle Bill, however, has other ideas...
Later in the episode, Barnacle Bill meets Betty Boop as a dog and says some rather horrible things to her in his singing, which is why this cartoon is not particularly suitable for children (although I am not sure if this cartoon was directed at family, children or adults).
It is a cartoon worth watching all the same and I recommend it to people who like old cartoons with singing pretty much instead of dialogue. Enjoy "Barnacle Bill"! :-)
