Cartoons of pirate ships always come complete with the usual icons - parrots, peg legs and pyramids of cannon-balls. That's artistic license rather than historical fact. The Royal Navy records that, on their ships at least, cannon-balls were stored in planks with circular holes cut into them - not stacked in pyramids. These planks were known as 'shot garlands', not monkeys, and they date back to at least 1769, when they were first referred to in print.
On dry land, the obvious way to store cannon-balls seems to be by stacking them. On board ship it's a different matter. A little geometry shows that a pyramid of balls will topple over if the base is tilted by more than 30 degrees. This tilting, not to mention any sudden jolting, would have been commonplace on sailing ships. It just isn't plausible that cannon-balls were stacked this way.
For those wanting a bit more detail, here's the science bit. The coefficient of expansion of brass is 0.000019; that of iron is 0.000012. If the base of the stack were one metre long, the drop in temperature needed to make the 'monkey' shrink relative to the balls by just one millimetre, would be around 100 degrees Celsius. Such a small shrinkage wouldn't have had the slightest effect. In any case, in weather like that, the sailors would probably have better things to think about than coining new phrases.

It has often been claimed that the "brass monkey" was a holder or storage rack in which cannon balls (or shot) were stacked on a ship. Supposedly when the "monkey" with its stack of cannon ball became cold, the contraction of iron cannon balls led to the balls falling through or off of the "monkey." This explanation appears to be a legend of the sea without historical justification. In actuality, ready service shot was kept on the gun or spar decks in shot racks (also known as shot garlands in the Royal Navy) which consisted of longitudinal wooden planks with holes bored into them, into which round shot (cannon balls) were inserted for ready use by the gun crew. These shot racks or garlands are discussed in: Longridge, C. Nepean. The Anatomy of Nelson's Ships. (Annapolis MD: Naval Institute Press, 1981): 64. A top view of shot garlands on the upper deck of a ship-of-the-line is depicted in The Visual Dictionary of Ships and Sailing. New York: Dorling Kindersley, 1991): 17.
That should do for starters ... if he still doesn't believe you, get back to me![]()
