The marina is situated near the site of the former Penarth Dock, which opened in 1865 primarily to export coal from the Rhondda Valley.
The tidal range in this part of the Bristol Channel is the second highest in the world, necessitating the lock gate system for safe access.
The Cardiff Bay Barrage, located nearby, keeps the water in the basin non-tidal and at a constant depth.
The marina features a 'boatcare' facility specifically designed for marine maintenance and engine repair services.
Penarth Marina is a 340-berth facility located at the mouth of the River Ely, serving as a gateway between the Bristol Channel and Cardiff Bay. The marina operates within a locked basin, maintaining consistent water levels regardless of the extreme tidal range of the Severn Estuary. It serves as a central hub for leisure boating, yacht maintenance, and waterside residential living. The site features a mix of modern architecture and converted historic dock infrastructure. A pedestrian footbridge connects the marina directly to the Cardiff International Sports Village. The marina is managed by boatfolk and provides comprehensive berthing services, including fuel docks and boatyard facilities. It remains a focal point for the Penarth waterfront, surrounded by contemporary apartment developments and dining establishments.
