MDL acquires 3.2-acre site to expand its Shamrock Quay Marina

MDL Marinas has announced the acquisition of a 3.2-acre plot at Lower William Street in Southampton, offering key expansion opportunities for its renowned Shamrock Quay Marina.

The newly purchased acreage, with prime waterfront and deep-water access, represents a highly strategic acquisition, enabling MDL to expand operations across both its Shamrock Quay and nearby Saxon Wharf Marina over time, giving both short-term and long-term development opportunities to extend the services on offer to its berth holders, visitors and other marina businesses.

Opportunities could include the expansion of MDL’s dry stack services, boat storage and increased car parking, as well as enhanced superyacht berthing and expanded boat manufacturing facilities. The land, officially designated as Millstone Point, is currently owned and operated by Oil Spill Response Limited and incorporates a vast building with offices, which MDL plans to rent out to potential tenants looking for prime office space within a marina setting.

“Today marks a pivotal moment for MDL Marinas as we proudly unveil our latest expansion in Southampton waters,” says Michael Glanville, Managing Director at MDL Marinas. “With the acquisition of the 3.2-acre plot, we’re not only securing prime waterfront real estate but also reaffirming our long-term commitment to growth and innovation. This strategic move positions Shamrock Quay to become one of the UK’s largest trading boatyards, demonstrating our dedication in serving the boating community with excellence, offering unparalleled facilities and services to all our marina customers.”

Situated in the heart of the River Itchen, with the backdrop of Chessel Bay providing scenic overwater views, MDL’s Shamrock Quay Marina offers the perfect blend of sheltered waters and access to world-class sailing conditions, with the bustling city of Southampton conveniently located a short distance away. Steeped in history, the 255-berth marina offers a raft of excellent services and facilities, including refit and boat building, specialist marine trades and a 70-metre superyacht berth, as well as popular bar and restaurant The Bistro Shamrock Quay.
