Description

The Canadian Code Sierra (S) Flag is part of the International Maritime Signal Flags used in Canada.
It features a white square with a blue square in the center, easily visible at sea.
When flown alone, it signals “I am operating astern propulsion.”
The flag is essential for alerting nearby vessels to a ship moving backward.
It follows the International Code of Signals, recognized worldwide by mariners.
Canadian vessels display it to ensure safe navigation and prevent collisions.
Proper use communicates vessel operations clearly to all mariners nearby.
Today, the Canadian Code Sierra (S) Flag remains a vital symbol of maneuvering communication and maritime safety.
