The Canal was extended, widened and deepened to allow for larger seagoing vessels. Ships from The Netherlands, Spain, Portugal and Italy sailed to Exeter for the successful wool trade. The 18^th century saw golden years for maritime Exeter with woollen mills working at capacity and wool imported from Ireland to deal with demand. The City Basin opened in 1830 to great celebration so vessels could load and unload regardless of the River Exe being in flood. However, as with many ports, the railways curtailed the working maritime industry. In the 20^th century, petrol, oil, timber, coal, cement and even potatoes passed through the port but commercial trade on the Canal dwindled and ceased altogether early in 1972.

Buildings around the Quay and Basin today house popular pubs, cafes, restaurants, activity centres and independent shops. The Canal can be enjoyed on foot, by bike and on the water. Canoes, bikes and water sports equipment can be hired.

The harbour has embarked on a working ‘heritage’ revival that reflects past maritime tradition and skills and looks forward to the future: providing berths for historic and traditional vessels; attracting boat building and traditional skills; encouraging more boat use by visitors and locally; navigation to be made more accessible; and opportunities for public engagement. In 2023 an East Coast smack and a replica Thames Barge were among the first visiting heritage vessels to be announced.
