"We will aim for gold. If you shoot for the stars and fail you will still end up in the clouds," Turfrey said.
Her long-term goal is to compete at Olympic Games level and next year she will study at Waikato University which will be another step towards that goal.
Fellow 17-year-old and Napier Girls' High School Year 13 student King, who is also in her fourth season in the sport, has been named in the national double sculls crew with Christchurch Girls' High School's Grace Shaw and is a reserve for the quad.
"I'm really excited but nervous at the same time," King said.
"I've rowed against Grace and now it's going to be fun to row with her. We hope to make the A final... anything other than that will be a bonus," King said.
King and Turfrey will leave the Bay on June 19 so they can stay with the rest of the New Zealand team at the Rob Waddell Lodge at Lake Karapiro and continue their secondary school studies at St Peter's School in Cambridge.
"We will spend four hours each day at school and the rest of the day we will be training," Turfrey said.
Earlier this summer King and Turfrey combined with Iona College's Kate Laracy and Woodford House's Jessica Norris to win gold at the club nationals in the under-18 coxless quad. Last summer they won gold in the under-17 coxless quad.
Turfrey returned home from the February club nationals with three medals. Her other gold was won with Laracy in the under-19 double scull and she also captured bronze in the women's club single.
Turfrey finished fourth in the under-18 single at Maadi Cup and King won the B final of the same event. King was also a member of her school's coxless quad crew which won bronze.
"We keep popping up these little gems," Hawke's Bay Rowing Club's club captain said referring to the fact it has been at least eight years since the club wasn't represented at a junior world championship.
"When it comes to making national finals the standard across our club is pretty high," Webb added.
King and Turfrey are among 10 girls in the 28-strong Kiwi contingent. They will leave for Rotterdam on August 12 for pre-competition training and their championships will be staged in conjunction with the world senior and under-23 championships.
The juniors were selected after a six-day trial camp which included a 2km ergometer test and rigorous seat racing. Eight Kiwi junior crews, girls coxless four, girls quadruple scull, boys double scull, boys quadruple scull, boys eight, girls reserve double scull, boys reserve pair and boys reserve single scull will be in action in Rotterdam.
Rowing New Zealand's High Performance director, Alan Cotter, said the athletes selected were the best seen at this level in recent years.
"The junior team is an important part of the pathway to representing New Zealand at the elite level and it's heartening to see such promising athletes joining the programme."
