Food reserves as a limit on warship endurance

How much reserve food did a first rate carry in its hold?

A first rate carried enough for months of extended operation, but fleet supply ships replenished those stores regularly because food was a fundamental endurance limit.

The listed weekly ration becomes immense when multiplied across almost a thousand people aboard a first rate. Warships therefore devoted major portions of their holds to food and still relied on an almost continuous movement of supply vessels to and from the fleet. Victory's Atlantic chase and return before Trafalgar illustrate how far a well-stocked ship could operate from what she carried aboard. Modern refrigerated spaces look different from Georgian barrels and sacks, but the endurance calculation remains recognizable. Ammunition, fuel, and food are the three consumable lines whose exhaustion can force a ship home even when the hull and machinery remain sound.
