Last night wasn't the most promising for a swim, with a decent southerly blowing up the harbour and not much water. The tide was dead low an hour before start time in race three of the Port Nelson Sea Swim Series.
Numbers were down a little, with 150 starters - still a healthy turnout.
Matai McGuinniety made it three in a row, winning the short swim of 250m ahead of Max Meffan, Brooke Matheson and Georgie Trengrove.
Big brother Kaiori McGuinniety led home the world's second-best under-23 aquathlon exponent as he sprinted to the line to finish in 12 minutes and 32 seconds, three seconds ahead of Harrison Dean, in the long race of just over a kilometre.
Kaiori McGuinniety travels to Auckland this weekend, where he joins the elite field for the first time to contest the Harbour Crossing, race two in the State Insurance Ocean Swim Series.
Luke Kelly, 15, showed some big speed gains over the winter, finishing third ahead of Matt Hansen.
Lisa Birkett will be hard to stop this summer, the 41-year-old mother taking fifth place, leading in a slew of teenage girls including Amy Coulton, Pip Dwyer, Libby Gray , Bailee Spriggs and Charlotte Handforth.
Only Kerry Mathieson had the speed to spoil the teenaged wave, the 44-year-old taking the fourth female spot.
Simon Kneebone, Ben Van Dyke and Ben Tuck and Jon Linyard were the other leaders in the male field.
On Sunday, swimmers take on a bigger challenge with the First Splash, the opening race in the Clements Endurance Series. The race begins at noon from Tahunanui Beach, finishing after 2km at the Nelson Yacht Club.
A short course of 600m starts at the Richardson St steps at 12.20pm. Competitors register at the beach at 11.30am. Information, entry and results at nelsonseaswims.co.nz
