The artificial reef would be constructed by dropping scores of sand-filled textile bags into the sea off Tolcarne beach, Newquay Bay, Cornwall.

Estimates put the cost of the scheme at �6m and talks are under way to attract potential investors.

Fistral beach at Newquay is already one of Europe's top wave riding spots - but the new reef could provide even better waves, says a study.

The site is one of the best our ASR team has studied for a surfing reef to create a world class surfing break

Feasibility study

New Zealand marine consultants ASR, headed by world surf expert Dr Kerry Black, of Waikato University, carried out the study on behalf of the Newquay Artificial Reef Company.

The study found the bay was "highly suitable" for a reef which would provide a massive boost for wave quality.

The study concluded: "The site is one of the best our ASR team has studied for a surfing reef to create a world class surfing break".

On ASR's own one-to-10 surfing wave quality scale the reef's waves would be seven against Fistral's four.

The quality of the reef's waves would rank with international breaks in Australia, New Zealand and South Africa.

The twin armed, arrow shaped reef would create 200 metre long surfing rides on each "arm".

Quality surfing conditions were likely to occur on 106 days a year with the new reef, said the study.

The consultants said the reef could last up to 100 years with maintenance.

Cash talks

Amateur fishermen would also benefit from fish which inhabited the reef.

The proposals have received support from both the Environment Agency and South West Tourism.

Talks are now to be held with bodies which may provide cash for the project including Cornwall Council and the South West Regional Development Agency.

Next steps include a public consultation, economic assessment, geo-technical investigations, reef design and an environmental impact assessment.
