‘“Science changes everything,” said Loudon, “even garden design.” With smoke, groans, shudders and roars, the vessel cast off and headed south. Its course had a deliberation unknown in the days of sail. There was no tacking to port or starboard. To France, its liquid path was as straight as an iron railway. The waves, though not large, had a short reach. Sunlit spray dashed across the ship's bow. Some passengers took refuge in the cabin. Others found sheltered places to sit on deck. Loudon confidently predicted an end to the age of sail’. This is a quote from The Claudians: gardens, landscapes, reason and faith: John Claudius Loudon and Claudius Buchanan, Tom Turner (Kindle, 2024). 
The Swift Steam Ship service was begun in 1822. It predated the construction of the Chain Pier by a year. Powered by a steam engine, it offered a much faster and more reliable alternative, significantly reducing travel time and boosting tourism between Brighton and Dieppe. This paved the way for the establishment of regular steamship services on this route between England and France.
The introduction of the Swift Steam Ship in 1822 marked a turning point in cross-Channel travel, drastically reducing the time it took to journey between Brighton and Dieppe. Unlike traditional sailing vessels, which depended on the whims of the wind, steamships offered a reliable and consistent schedule, ensuring that passengers could plan their trips with greater certainty. This innovation not only boosted tourism but also contributed to the economic growth of both regions by facilitating faster movement of goods and people. The success of the Brighton-Dieppe route demonstrated the broader potential of steam power in maritime transport, accelerating the decline of sail-driven ships and heralding a new era in seafaring history.
