The town's glory days were during the period of the 1750s to c. 1864, when ship traffic was at a high growth rate with trade to the Mediterranean Sea, China, South America, and Australia. It possessed a good harbour, which afforded shelter for a large carrying trade, Aabenraa having the Danish monarchy's third-largest trade fleet, after Copenhagen and Flensborg. The city had a number of well-known shipbuilding yards, which were known for their fine ships. The most famous of these was the clipper "Cimber," which in 1857 sailed from Liverpool to San Francisco in 106 days. Fishing and various small factories also provided occupations for the population.
