So....Here is a full keel
antique technology Sailing cargo ship performance for you.
Built in 1954 the Lightning
226'×44'×26' [loa 243'] and tonnage: 2084 tons
1854 March 1
On the this day the Lightning
sailed 436 miles, which is the longest day's run recorded by a sailing ship.
March 1. — Wind
S., strong gales; bore away for the North Channel, carried away the foretopsail and lost jib
; hove the log several times, and found the ship going through the water
at the rate of 18 to 18½ knots per hour; lee rail under water
, and the rigging
slack; saw the Irish land at 9:30 p.m. Distance run in the twenty-four hours, 436 miles.
From the Abstract log
Her run from the Mersey to the Equator occupied 25 days, and from the parallel of the Cape to the Port Phillip Heads 30 days; indeed, such was the nature of the winds, that the topgallantsails never had occasion to be furled during the entire passage
, neither was there occasion to reef the topsails. With the exception of five days, when the ship logged 332, 348, 300, 311, and 329 knots
respectively per day, no extra-ordinary distances were logged.
On the 13th and 14th, strong and south-west winds were experienced, and she ran 351 and 354 miles per day respectively.
Now before I get scolded, I understand the length to width ratio, and Canvas
area to wetted surface (Drag) coefficient. Buy really? we have a hard time beating these age old ships with way to high center of gravity, rigging
that was 30% of the entire ship weight, keels that were not only full length of the entire ship, but internally ballasted, (Usually using mostly the cargo for ballast) oh yeah, they were sailing at these speeds with a FULL weight of cargo on-board, down wind
Humm, I often wonder if we built a modern clipper ship out of aluminum hull
, carbon fiber masts, and to be fair with performance cruising yachts, instead of using cargo for ballast, we put a external lead keel
and latest sail and rigging technology, could we see speeds double?
