By the early 1850s the company began to rely less on wood ship or railcar building for its income. Machine shops, office buildings, wharves, carpenter sheds, boiler shops, blacksmith shops and cranes were added in the first five years of the decade. As the firm's reputation grew, more orders for steamboats came in from across the country. Charles Morgan, a New York shipping magnate, purchased his first ship from Harlan in 1856. Morgan would eventually become one of the largest customers for Harlan & Hollingsworth, ordering over 31 vessels by 1878.
