Why sailing navies could not economize by starving crews

How did rations compare among British, French, Spanish, and Russian sailing navies?

The details differed, but none could underfeed crews severely without losing the labor, morale, and loyalty needed to fight the ship.

The panel describes British, French, Spanish, and Russian naval rations as broadly comparable in purpose even when drinks and individual foods differed. Sail handling, gunnery, and ship maintenance demanded continuous physical effort, so underfeeding sailors directly reduced the fleet's power. The analogy is even sharper for oared vessels, where the rowers are the propulsion system. Starving and beating enslaved oarsmen weakens the engine and gives them a reason to support an enemy boarding party. Food policy therefore connected logistics with performance, hygiene, loyalty, and combat survival.
