Barnett, who steers the boat and controls the mainsail, has made rapid progress in sailing since he started just three years ago.
"We have a two-year plan together. We want to do well at this year's youth worlds and want to do even better next year so we are building all the time," Barnett said.
"In Cyprus we don't really know what the quality of the fleet will be like so we are thinking of process goals at the moment, in terms of making sure we do techniques right and the processes are good."
The two Tauranga sailors are spending the school holidays training in Auckland with their coaches Jim Maloney and Ed Smyth to ensure they are ready to take on the world's best young sailors in July.
Ian Neely, Yachting New Zealand's Talent Development Manager, is excited about the team's prospects in Cyprus.
"To be selected for the NZL Yachting Trust Youth Team is tough," said Neely.
"These sailors have worked hard to earn this honour."
