‘I think it’s great, as it would teach people to swim, give disabled people access and be an assistance for winter swimmers,’ Mal Hynes, an Iceberg member since 1962, said from his home near Bondi Junction last week.

For the past 10 years, Mr Hynes has advised Cottesloe Surf Life Saving Club member Tom Locke about his proposal that would give WA swimmers a sheltered sea pool on the north side of Cottesloe Groyne.

Last Saturday, Iceberg and Cottesloe SLSC Crabs swimmers continued their 30-year rivalry, dubbed ‘Mates across the nation,’ in a friendly relay at Cottesloe Beach.

The next day about 450 winter swimmers, aged 18 to 88, from across Australia competed in the 38th annual Winter Swimming Association of Australia Championships at Challenge Stadium.

‘WA’s winter swimming talent would improve with a sea pool because you’re all swimming in heated pools now,’ Iceberg captain Matt Barry said.

University of WA researchers at the Centre for Water Research are using real- time wave and wind data from a buoy about 300m south of the groyne to test computer models of sea pool designs.

The models will gauge potential erosion patterns and ability of the pool to be flushed with fresh seawater in all conditions, before a final plan expected at the end of this year.

Mr Locke said the design work had progressed to considering the structure of the extension, with concepts ranging from smaller rocks that replicated the look of the existing groyne to a narrower barrier comprising the pool’s outer wall.

‘The favoured option is where it looks like a series of small piles around the perimeter and rocks will be placed beside each pile,’ Mr Locke said. The design would allow a smoother surface inside the pool to protect swimmers and a rougher outside wall to absorb wave energy.
