In every shot showing the boat, it simply reads "Minnow" on the side. However, in the show intro, it reads "S.S. Minnow".
Although the SS Minnow is completely destroyed in this installment, this is ignored in future ones. She is mentioned as being intact in several later installments.
Obvious voice dubbing in all beach scenes. This occurs in every location scene throughout the first series. Mikes are used on the color episodes, but the location scenes are limited to the lagoon.
In the beach scene where the Howells find Gilligan and Skipper glued to the boat, as well as the later christening debate, the shots that include the hills behind the boat have typical Southern California scrub, not tropical plants.
