"If you're not going there to win it, what's the point? It's our first youth worlds but we are going to try to achieve a top result."
Ten Have, 17, is aiming for a top 10 finish in China and to get the opportunity to go to the prestigious Aarhus RSX Open Worlds in Denmark in July.
She has been trying to spend as much time as she can on the water ahead of the worlds in China, training four times a week as well as attending P2P [Pathway to Podium] workshops.
It has been a stellar year for her Tauranga Yacht and Boat Club teammate Van der Zalm, 17. He won the 2017 NZ RSX under-19 nationals to go with the 2016 NZ Techno 293 under-17 title.
Getting the opportunity to race at the Youth Worlds is the highlight of his year.
"I felt excited that my hard work had paid off and that I get to race against the best in the world," he told Yachting NZ.
The Youth Sailing World Championships is the pinnacle regatta for sailors aged 14-19 and last year was hosted at Torbay when 379 youngsters from 65 nations competed across the nine classes.
New Zealanders have won 51 medals at the youth worlds since the first in 1971 and many, including Chris Dickson, Russell Coutts, Jo Aleh, Blair Tuke, Stu Bannatyne and Tom Ashley, have achieved considerable success in their sailing careers.
