His voice actor was British actor Lee Cornes. Lee also voiced Grampus, Billy Shoepack the Alligator tug (Who is the only Up River Tug he never met), and Boomer. He speaks with a neutral English accent.
In the buzz books, The Coast Guard was referred to The Customs Launch, and in the American spinoff to tugs, Salty's Lighthouse, The Coast Guard was renamed Cappy.
The Coast Guard had his own messenger who was rarely seen. He is a small speed/motor boat with a shrill whistle that sends messages for the Coast Guard. He made his first appearance in the pilot, and in this episode, he is shown next to the Fire Launch during the scene with Warrior towing The Duchess.
His voice actor was British puppeteer Don Austen.
The same model was also used for the mad speed boat that caused the accident in Quarantine.
