In 2016 Mackay and Wilkinson won the Red Bull Foiling Generation World Final in the United States. With this victory Mackay became the first Napier club member to taste world championship glory since Barry Finlayson and Ian Norrie won the 1980 Flying Fifteen World Championship.
Former Woodford House student Mackay's 2016 title was one of the highlights of the club's 125th anniversary year. Mackay and Wilkinson are in their fourth year of racing in the Nacra 17 class where 5.5m (18 foot) long Flying Phantom foiling catamaran boats are raced and in 2016 were the under-23 world champions.
Yachting New Zealand's communications manager Michael Brown said as a result of their selection Mackay and Wilkinson will receive additional funding because they are in the country's top squad.
"They are tracking well."
The 2018 New Zealand sailing team has a fresh look to it with three additions to last year's squad, Laser class sailor Tom Saunders and Mackay and Wilkinson. The squad has increased in size from 11 to 13.
Two-time Olympic medallist Jo Aleh is the only name missing from last year's team. Aleh has joined the workforce and is not campaigning, although she has not retired from the sport.
Peter Burling and Blair Tuke have been named, although the pair have not yet made a final decision on whether they will attempt to defend their Olympic title in Tokyo. They are still competing in the Volvo Ocean Race.
Other members of the squad are: Sam Meech (Laser), Josh Junior (Finn), Alex Maloney and Molly Meech (49erFX), Paul Snow-Hansen and Dan Willcox (men's 470).
Yachting New Zealand high performance director Ian Stewart is excited about the ability within the 2018 team and said this year is about results.
