What is the specific decree in changing larboard to port?

The change from "larboard" to "port" was officially adopted by the Royal Navy in 1844 to avoid confusion with "starboard," especially in noisy environments. The term "larboard" could be misheard as "starboard," leading to potentially dangerous navigational errors. The switch to "port" provided a clearer and more distinct terminology for the left side of a ship when facing forward. This change has since been widely accepted in maritime language globally.
