Samuel Amos Quatell, 19, vanished from the fishing vessel ISE II on March 12, 1983, while the boat worked near Steep Island in Seymour Narrows, the strong-tide channel between Quadra Island and Campbell River. Crew members last saw him near the stern; when he could not be located the alarm was raised and search and rescue conducted an extensive sweep of the turbulent waters.

The currents in Seymour Narrows are noted in the file as extremely strong and capable of carrying a person a great distance quickly, which greatly complicated the search. Despite determined efforts, no sign of Samuel was ever found. He is described as an Indigenous male, heavy build, dark complexion, short black hair, brown eyes, 5 feet 6 inches tall and about 161 pounds, with a scar on his right thumb and the tip missing from his left ring finger. He was wearing a black leather jacket, blue denim pants, and black cowboy boots when last seen.

The Quadra Island RCMP investigation has not produced a definitive explanation for his disappearance. If anyone knew Samuel, worked on that boat, or has information about Seymour Narrows on March 12, 1983, please come forward.
