The Mimi's crew included Captain Clement Tyler Granville (played by actor/scientist Peter Marston) and his grandson Clement Tyler, played by a young Ben Affleck. Gadsden's Anne Abrams was a marine biologist working with her colleague Ramon Rojas (played by Edwin de Asis) to complete a census of humpback whales. Abrams hired Captain Tyler, the owner of the Mimi, to take them out onto the ocean to work on the census.
Along with Rojas, Abrams is accompanied by her graduate research assistant, Sally Ruth Cochran (played by actress Judy Pratt), who is deaf. Each scientist invites a high-school student to assist in the census. The two students they select are Arthur Spencer (played by Mark Graham) and Rachel Fairbanks (Mary Tanner). At certain points in each episode, these two actors, in addition to Affleck, would step out of character to conduct interviews with actual scientists about the work they do.
In "The Voyage of the Mimi," Anne Abrams is an educator. The target audience of middle-school students were meant to identify with the three teen characters. The children in the show would ask questions about science, which would then be answered by the Abrams character. In this way, Abrams was used as a device to impart educational information to the viewers in a way that would engage and interest them more than simply reading from a textbook.
A subsequent series, "The Second Voyage of the Mimi," was produced a few years later, in 1988. The premise was similar, but this time Captain Tyler and his boat were hired by a team of archaeologists. Anne Abrams and her team were not involved in this second journey, and did not appear in this iteration of the series. "The Voyage of the Mimi" was one of the few screen credits for actress Victoria Gadsden. According to the Internet Movie Database, her only other credit is a 1983 Portuguese comedy called "Sweet Pea."
