Winning Olympic sailing gold in the 49er class is not the only exclusive club Peter Burling and Blair Tuke are aiming to join.
Like Sir Russell Coutts before them (he won gold in the Finn class at the 1984 Los Angeles Olympics then went on to America's Cup glory), Burling and Tuke are members of Emirates Team New Zealand's 2017 Cup challenge and would dearly love to add that to an increasingly bulging trophy cabinet.
As well as Coutts, just two other gold-medal-winning sailors have gone on in the modern era to win the America's Cup - most notably, Englishman Sir Ben Ainslie who won four successive golds in 2000, 2004, 2008 and 2012 Olympics before joining winners Oracle as tactician in the 2013 cup races off San Francisco. He has formed his own team - Ben Ainslie Racing - to compete in Bermuda in 2017.
The other who has achieved the "double" is Australian Tom Slingsby, winner of the Laser class gold at London in 2012 and strategist for Oracle in 2013. Andrew Simpson of England, who won gold in the Star Class at Beijing in 2008, was a member of the Swedish Artemis challenge in 2013 but was tragically killed when the catamaran capsized in a training sail off San Francisco.
Burling and Tuke will be hoping they can fashion as impressive a cup record as countryman Coutts. As skipper/helmsman in three Americas Cup campaigns - two for Team New Zealand in 1995 and 2000 and one for Alinghi in 2003 - Coutts was never beaten on the water, winning all 15 races he started.
In the last two campaigns in 2010 and 2013, Coutts as Oracle Sailing's chief executive, headed up two victorious Oracle campaigns including the heart-breaking come-from-behind 9-8 victory over Team New Zealand in San Francisco three years ago.
Burling and Tuke's gold medal- which was achieved with a race to spare - follows their silver medal finish in London in 2012 and four successive world championships in 2013, 2014, 2015 and 2016. In that time the pair have totally dominated the class, winning 27 out of 28 major international regattas.
They also join another club - those whose Olympic victories in Rio have led to gold ATMs sprouting at ANZ branches across the country. ANZ, a major sponsor of the New Zealand team, is turning ATMs to gold in the winners' home towns every time gold medals are won.
Thanks to Burling and Tuke, the latest ATMs to go gold are at 1 Grey St in Tauranga - Burling's home city - and at Kerikeri in Northland where Tuke lives.
Already ATMs at branches in Dunedin, Cambridge and Whakatane have gone gold, following Hamish Bond (Dunedin) and Eric Murray's (Cambridge) rowing victory, Mahe Drysdale's (also Cambridge) win the in the single sculls and Lisa Carrington's (Whakatane) second Olympic gold in the 200m canoeing event.
