Where 1838 fits
Why 1838 is special
Steam crossings had been claimed before under partial sail. Sustained steam power across an ocean made scheduled transatlantic service possible, which sail never could.

Technology & computing
Sailing packets crossed the Atlantic on the wind's terms. Steam made the crossing time predictable from 1838, which is what allowed timetabled service and eventually the liner trade.
