Plans for a major new marine sports centre on the Mumbles waterfront have been submitted to Swansea Council – alongside proposals for 12 luxury flats on the site of the existing Mumbles Yacht Club to help fund the development.
The “Centre for Marine Sporting Excellence” would be built at Knab Rock, next to Verdi’s café, just yards from the popular slipway.
It would include training and coaching facilities for sailing, rowing and coastal sports, a tidal bathing pool, boat and equipment storage, public toilets, a Changing Places facility and flexible community rooms.
The centre would also house a 120-seater function room – described in the plans as suitable for conferences, training events and weddings.
But to help pay for it, the existing Mumbles Yacht Club building across Mumbles Road would be demolished – and replaced with 12 luxury mezzanine apartments above an undercroft car park.
Documents submitted to Swansea Council show that the apartments – 10 standard flats and two penthouse suites – would be expected to sell for between £500,000 and £650,000 each, generating an estimated £6.3 million to £6.5 million.
That money would help fund the marine centre, which is currently estimated to cost £4.5 million to build.
Mumbles Yacht Club, founded in the 1930s, is also home to Mumbles Rowing Club, founded in the 1880s – a centre of excellence for coastal sculling that attracts Team GB athletes.
Together, the clubs have around 350 to 400 members.
The yacht club has held a public consultation that drew more than 500 responses, with almost all in support of a new watersports centre, according to the club.
Commodore Richard Woffinden said the club was excited about the future. “There’s a long way to go but we are really excited about the future of Mumbles Yacht Club and our rowing club,” he said. “It would be great to be part of a centre where clubs of all sorts can work together to create opportunities for our community to join us on the water.”
The proposals also flag potential future ambitions for the site – including a half-tide harbour and a tidal swimming pool – as part of a wider vision for enhancing the Mumbles waterfront.
The club has indicated it may also explore grant funding to upgrade the proposed centre into a national-level coaching facility for Wales and the UK.
Plans submitted to the council acknowledge the significant constraints of the site.
The yacht club building lies within the Mumbles Conservation Area, while the proposed apartment site sits within the Gower Area of Outstanding Natural Beauty (now known as the Gower National Landscape).
The flats would be partly built into the limestone cliff face – a designated Safeguarded Limestone Resource and an internationally recognised dark sky community, requiring strict controls on lighting.
The Grade II listed Bristol Channel Yacht Club sits just 30 metres away from the proposed apartment block, and the marine sports centre site is within Flood Zone 3 – meaning major flood risk constraints apply.
Council planning officers have responded with a mixed verdict on the proposals.
Officers said they applauded the aspirations to provide a new high-quality Centre for Marine Sporting Excellence, recognising its potential community and sporting benefits.
But they raised significant concerns about the principle of developing 12 luxury private flats on land that extends outside the Local Development Plan settlement boundary – which would normally only be permitted as “enabling development” with substantial heritage benefits.
The officers also said insufficient information had been provided to justify the scale, massing, siting and design of the buildings, or to demonstrate proper compliance with placemaking principles.
Concerns were also raised about lighting impacts on the Gower’s dark sky designation, parking levels, residential amenity, green infrastructure and the robustness of the proposed enabling development model.
The proposal also appears to be contrary to TAN 15 – Welsh Government planning guidance on flood risk.
The yacht club will now respond to the points raised, develop a business plan and explore funding in more detail.
The plans come at a time when several other major waterfront proposals are under development across Swansea Bay. A separate tidal pool is being proposed near the Civic Centre as part of a major transformation by Urban Splash, while Eden Project-style proposals from Xanadoo are also being explored for a Swansea site.
The application is currently at the pre-application stage with reference 2026/0063/PRE on Swansea Council’s planning portal.
A formal planning application is yet to be submitted.
