About Us

Flat holm Ferry

Bought by Cardiff Cruises in 2020, this boat was purpose built by Mustang Marine in 1989 to sail between Flatholm Island and Barry, where it was originally located. 

When the Glamorgan council divided into the Vale and Cardiff, the boat remained the property of the Vale Council, although the island became the responsibility of Cardiff. The then new Cardiff Harbour Authority ‘leased’ the boat from the Vale but by the year 2013 they had neglected the boat and the cost of maintenance became too much for the council. The Vale council then sold the vessel to Cardiff for a nominal scrap value and was put up for auction in 2019.
In 2020 Lewis Alexander went into drydock for a complete overhaul and to be re-certified so that once again she can serve the island and operate in the Bristol Channel.



You will board in Mermaid Quay at the heart of Cardiff Bay on Marianne and enjoy a relaxing 45 minute trip around the area where you will see the Senedd, Norwegian Church and many more famous sights. You can also board at the Barrage where we pick up further passengers 15 minutes later than the times advertised
