Captain Adrian Blancard "Fishhead" is the captain of the N.E.R.D.S. sailing crew. He was a member of N.E.R.D.S from 1973 to 1983. According to matolda, he was a total hottie.
Error: In Book 2 Ruby mentions that Fishhead was on the team from 1973-1983, but it is mentioned many times that N.E.R.D.S. was founded in 1977.
