The U.S.S. Constitution (Old Ironsides) as a combat vessel carried
48,600 gallons of fresh water for her crew of 475 officers and men.
This was sufficient to last six months of sustained operations at sea.
She carried no evaporators (fresh water distillers).

However, let it be noted that according to her log, "On July 27, 1798,
the U.S.S. Constitution sailed from Boston with a full complement of
475 officers and men, 48,600 gallon s of fresh water, 7,400 cannon
shot, 11,600 pounds of black powder and 79,400 gallons of rum."

Her mission: "To destroy and harass English shipping."

Making Jamaica on 6 October, she took on 826 pounds of flour and 68,300
gallons of rum.

Then she headed for the Azores, arriving there 12 November. She
provisioned with 550 pounds of beef and 64,300 gallons of Portuguese
wine. On 18 November, she set sail for England.

In the ensuing days she defeated five British men-of-war and captured
and scuttled 12 English merchantmen, salvaging only the rum aboard
each.

By 26 January, her powder and shot were exhausted.

Nevertheless, and though unarmed, she made a night raid up the Firth of
Clyde in Scotland. Her landing party captured a whiskey distillery and
transferred 40,000 gallons of single malt Scotch aboard by dawn.

Then she headed home.

The U.S.S. Constitution arrived in Boston on 20 February 1799, with No
cannon shot, No powder, No food, NO rum, NO wine, NO whiskey and 38,600
gallons of stagnant water.
