Steamship groundings were relatively common on the English coast in the 19th century. Steamships were a new and constantly evolving technology. Propulsion and navigation systems were not as reliable as they are today, which increased the risk of accidents.
Weather conditions could change quickly, especially at sea. Storms, fogs, and strong currents could easily throw a ship off course and push it towards the coast.
Maritime traffic was constantly increasing in the 19th century, which increased the risk of collisions and groundings.
Navigational aids, such as lighthouses and buoys, were fewer and less effective than they are today.
Nautical charts were not as accurate as they are today, and sailors did not always have a thorough knowledge of the coastline.
