When side boys are paraded, what is the minimum number required?

When side boys are paraded, the minimum number required is two. This tradition is rooted in naval customs where side boys are designated to salute and assist senior officers as they come aboard or depart a ship. The presence of two side boys ensures a proper ceremonial gesture, allowing for the transfer of honors in a dignified manner. Each side boy represents a part of the function, typically positioned on either side of the route taken by the officer, reinforcing the respect and protocol integral to naval heritage. The use of two also facilitates a consistent representation of the tradition across various naval ceremonies.
