Where is the starboard side of the transom?

The starboard side of the transom refers to the right side of the back end of a boat or ship when facing forward. In nautical terms, "starboard" indicates the right side, while "port" refers to the left side. The transom itself is the vertical section at the stern that connects to the sides of the hull. Thus, the starboard side of the transom is the right-hand portion of that rear vertical surface.
