Tauranga sailor Peter Burling and Blair Tuke have obliterated the field to clinch their second straight 49er world title at the ISAF Sailing World Championships in Spain.

With the crown already in the bag, the pair continued their dominance on the sixth and final days racing winning the medal race - finishing 46 points ahead of their nearest rivals from Denmark.

Overnight's win gives them six wins across the 13 race series only finishing outside the top six in race 11 which was interrupted for them in an accidental collision.

'We wanted to come out and put on a good show today and give the fans back home something to cheer about as well, and we came out firing and sailed a really good race. We really enjoyed that last one,” says Burling.

Asked what makes the difference between and the rest of the fleet Tuke puts it down to a lot of hard work and 'really nailing it” during the competition.

'We've sailed really well all year, but to perform at the event that you want to is really pleasing. It's not just one thing, but we're executing a lot of things well, and its pleasing to put it on at the World Championships.”

Burling says the longer a pair sail together the stronger the partnership and communication grows – something Tuke and himself have in their sailing arsenal.

'We're really enjoying it and we feel like we're getting better all the time and we just want to keep improving.”

Fellow Kiwi teammates Marcus Hansen and Josh Porebski finished the series in 16th place after placing 17th in the overnight race and outside the top ten medal race cut off.

Logan Dunning-Beck and Jack Simpson ended up in 25th.

In the women's 470 class Jo Aleh and Polly Powrie claimed silver and in the 49erFX Alexandra Maloney and Molly Meech finished outside the top 10, missing out by two points on the medal race.

The 2013 World Champions suffered in the standings from mixed results through the qualifying and finals series, but their performance wasn't without highlights.

Maloney and Meech took 3rd in race one, and a 2nd in race five, and the young kiwis will no doubt take the lessons from this event to build on.

In the Nacra multihull class Tauranga's Jason Saunders and Gemma Jones and Jason Saunders claimed 4th in their medal race earning themselves a top five finish – another personal best achievement for a New Zealand crew here in Santander.

Jones and Saunders paired up to campaign this new Olympic class in 2013, and are up against some experienced and accomplished sailors from around the world.

The NZL Sailing Team has also qualified New Zealand for the 2016 Rio Olympics in all ten Olympic sailing events as a result of their performance at this event – an excellent position to be in two years out from the next Olympics.
