Poolbeg Marina is a 100-berth facility operated by Poolbeg Yacht & Boat Club, situated on the south side of the River Liffey in Ringsend, roughly 3 km from Dublin city centre and close to where the Liffey and Dodder meet the sea.

It can accommodate vessels up to 20 metres LOA with drafts of up to 2. 4 metres, and offers unimpeded access to the sea. The marina is built to international standards with floating pontoons, secure access gates, CCTV, and a seaflex mooring system.

Each berth is served by water, electricity, and Wi-Fi, and pump-out and diesel fuel facilities are available on site. The clubhouse provides toilets, showers, and a lounge bar. Visiting boats are welcome, and the club monitors VHF channels 37, 12, and 16.
