‘Fins’ appears on Jimmy Buffett’s ninth studio album, 1979’s Volcano. This is one of his most popular songs, though it made it to only #35 on the Hot 100. Buffett has never been huge on the charts, despite having one of the most fervent fan bases in popular music.
This song is about a midwestern woman who heads to the islands for escape only to find herself preyed upon by lascivious men, characterized as “sharks that can swim on the land.” It is one of eight songs Buffett played at just about every one of his many concert performances.
