Good Night Sweet Skipper - S1-E5
Revealing mistake: In the end scene, as Gilligan chases the bug, trying to quiet it, you can see the lines in the gourd where the hole will be after he hits Skipper with it.
Revealing mistake: As the gale force wind lifts Gilligan, you can see the outline of the harness under his clothes and can make out the wires holding him up.
Continuity mistake: In this episode, the damage to the boat is different than seen in "Two on a Raft." Also, there was a vessel number on the bow of the boat that is absent in this episode.
Revealing mistake: When the shark takes a second bite of the raft, you can see the bite before it's taken.
Other mistake: Where Gilligan is yelling to everyone "Don't get on the minnow, the glue won't hold!" you can see a pack of Chesterfield cigarettes sticking out of his left front pants pocket.
Little Island, Big Gun - S1-E18
Visible crew/equipment: Gilligan shoots a bag of money in a tree with an arrow. As the money falls to the ground you can see a fan in the lower left corner of the screen aimed up towards the tree.
Other mistake: When the headhunter is about to chop a tree Gilligan is behind, he yells. The actor has metal fillings in his teeth. Headhunters would not likely have a dentist.
Continuity mistake: As Mr. Howell tells his story, the table Ginger is on rocks to the point the canteen beside her falls off. A second later, she's drinking out of it.
Visible crew/equipment: As the camera looks at Skipper and Gilligan, after the tossing of the sail, the edge of the studio tank is visible for a few seconds in the background.
Continuity mistake: After the shark bites Gilligan's paddle and he holds it up, the amount of wood between the handle's connection and the bite differs from shot to shot.
Other mistake: As the girls are trying to land their catch, the Skipper comes by and starts to help. Although he was walking by, when he starts to help, his pants legs are already wet from previous takes.

Continuity mistake: At the beginning of the episode when everyone is listening to the radio the professor is shown standing up and in the next shot is sitting down. (00:02:50)
Other mistake: At the beginning of the episode when the Skipper wakes up on the boat this scene is actually from the original pilot, as you can see the 3 different actors that played the part of the professor, Ginger, and Mary Ann. (00:01:20)
Suggested correction: The original actors ARE shown, true. However their characters slightly differred in the original pilot. They were known as a high school teacher, Ginger, and Bunny.
Continuity mistake: While the castaways are standing around while their clothes dry, Mary Ann is not wearing any shoes. As the scene continues she is shown standing wearing black shoes. (00:05:00 - 00:06:00)
Continuity mistake: When the SS Minnow is shown beached on the deserted island, it's seen leaning on its left. At the ending credits, the Minnow is shown completely upright.
