Bob Denver who played Gilligan played a beatnik character in an earlier show called "The Many Loves of Dobie Gillis" but that was in the late 50's/early 60's.

"Gidget" was a 1960's beach-culture sitcoms with Sally Fields

"Three's Company" took place in in Santa Monica and the character John Ritter played was clumsy like Gilligan

Gidget was set the early 60's Surf and Beatnik culture of California

that 70's show?

Gidget is my best guess.

the main character is very similar to giligan on gilligans island. the show revolves around a hippy beach culture genre. Can you give me the name of the show and the main character (tv character name)?
