In todays military, we have many unique customs. What is not realized is that what is now custom formely had a real purpose. Take the use of Side Boys to welcome a ranking visitor aboard a military vessel. It is the task of assigning two, four, six, or eight men to line both sides of the gangplank based on the ascending rank of the officer visiting the vessel, with two being assigned for ensigns and Lts, up to eight for admirals and above. More rank, more honor guard, right? But this system originally served a darker purpose....
this custom came from the British Navy of the 17-18 century. back then, men did not often have the luxury of walking on to their ships: most had to transfer from a small boat to the larger ship by Ladder, or by a device called a bosun's chair, which was essentially a seat attached to a yardarm by a block and tackle. Here where the revelance comes about
: the younger and less rank you had, the lighter you were. thus, a light midshipman or LT needed only two men on the haul rope, while a long endurance and often very stout Admiral, having eaten everything and then some over their forty year carreers, tended to need eight men to pull them up. additional jobs, such as availng themselves to steady the person after getting them to the deck, and helping with the persons luggage and other dunnage they would bring with them, also necessitated a required number of hands based on their weight or amounts of belongings collect thruout the years.
