The Carolina or La Carolina or Carolina II was the second steamship to sail between Trieste and Venice , both of which were part of the Austrian Empire at the time . It was probably named after Empress Karoline Auguste of Bavaria , the fourth wife of Emperor Franz I. It replaced the steamship of the same name Carolina and received its steam engine.
Morgan Feathering Wheel (also Morgan Paddle Wheel)
The owner was the "IR Privilegiata Compagnia di Navigazione a Vapore tra Trieste e Venezia", which belonged to the American consul and trader John Allen from Philadelphia and the Englishman William Morgan. The ship had a wooden hull and was equipped with a two-cylinder steam engine from James Cook from Glasgow . On April 15, 1821, the ship sailed for the first time from Trieste and Venice. After that, the Carolina drove this route, for which it took 19 hours, twice a week.
In June 1829 Morgan had the "Morgan Feathering Wheels" named after him installed on the ship. These special paddle wheels were invented and patented by Elijah Galloway in 1829 . With these paddle wheels, the blades plunged vertically into the water when the wheel was rotated and also emerged vertically again. This made the bike work much more effectively. The "Morgan Feathering Wheel" can be seen as the answer to Josef Ressel's patent on the propeller.
