Baddeley said the German- designed boat was being used by Adam McKernan, Sam Beazley, Josh Ackers and Alistair Clark as they prepare for the North Island championships and National regatta in February.
Baddeley said that while the Olympics had helped, rowing in Whangarei was popular before New Zealand's success.
"Our club over the last three years has picked up dramatically. We've gone from around early 20s to about 50 members now."
New Zealand will send its biggest ever rowing team to the Rio Olympics, and Baddeley hopes a few of Whangarei's up-and-comers who are using the new boat will be in the frame.
"But it does tend to be around age 22 or 23 when rowers tend to come into their own, because it's a physical maturity thing. I can see the likes of Adam McKernan and Sam Beazley doing quite well in years to come."
McKernan and Beazley earlier this month upset a Youth Olympic-bound Vanuatu team by 0.36 of a second to come out on top at the 2012 Christmas Regatta - the largest regatta in New Zealand history with 2000 athletes competing.
One person who will definitely be in the frame is Olympic legend Mahe Drysdale who will look to defend his single sculls title after this week announcing his intention to continue in the sport until 2016.
The 34-year-old will take a six-month sabbatical from rowing and will be back in the boat at Lake Karapiro for trials in July 2013, aiming to gain selection for the following month's world championships in South Korea.
Six out of NZ's nine rowing Olympic medallists will be back into training by next month.
