Fin and Foil

Starting with the:

Gran Canaria Dunkerbeck Speed Challenge

Because of the ongoing Covid-19 restrictions we decided to continue with the online format and make it even bigger: The Dunkerbeck Speed Challenge Virtual Global Tour consists of 3 events:

Each period will have their winner and rankings.

Also we give a special topic to each period
Period 1: Who’s the fastest on 1/2hr sailing (tribute to Defi long distance race)
Period 2: Who’s the fastest alpha racer (summer fun, good vibes)
Period 3: Who’s the fastest on 500 m (because it’s the Lüderitz World record time)

In each Period we will award Top 3 in the following categories:
OPEN Male & Female · Grand Master (51-60) · Super Master (61-70) · Ultimate Master (71-99) · Youth (0-10) · Junior (11-14) · Junior Plus (15-18) · Foil (from www.gps-foilsurfing.com)

Gran Canaria Dunkerbeck Speed Challenge – Virtual WORLDWIDE Speed Windsurf Event

Period 1: 21.05.-21.06.20 / Period 2: 01.07.-31.08.20

This year, in this exceptional situation that the whole world is experiencing with all the limitations that are being imposed on us, we are happy to continue with the competition format that we have been carrying out since 2015 and to make it even more interesting for all windsurfers.

The online gps- based raceing format on www.gps-speedsurfing.com is a perfect way to compete and maintain the social distancing at the same time.

Dunkerbeck Gran Canaria

Due to current COVID-19 restrictions unfortunately the Defi –Event, where we are organiszing since six years “a race in the race” had to be postponed to next year but online we can compete!

Gran Canaria Dunkerbeck speed challenge 

To make it more accessible to all windsurfers in the world and because there are many more spots where you can do this distance, we decided to rank the fastest average speed on 250m.

Dunkerbeck Windsurfin

As a tribute to the Defi Wind we’ll have a first period from the 21st of May till the 21st of June and as an ADD ON a second period from the 01.07. till the 31st of August.

Because it’s also our main motivation to mobilize the entire windsurfing community and regain relative normality through our sport as soon as possible using current technology to compete together from any country in the world without traveling, while promoting windsurfing as an ecological sport and healthy lifestyle.

Make sure that you don’t miss a period because the winners will be the ones with the fastest Average of the two rounds.

After being in lockdown for several weeks we are sure that we are all really looking forward to get back on the water.

Dunkerbeck Speed Challenge

Whats NEW this year?

this year we’ll also rank:

  • YOUNG GUNS (all kids under 18 years- from 2002 on)
  • GRAND MASTER+ (50 years+ born in 1970 and later)
  • FOIL

(what’s alpha race? A small explanation for those who do not know what it is, is to do a distance of 250mts a jibe and another 250mts back. The trick is that there can be no more than 50m between the starting point and the return point, and this is where the ability of the windsurfer to set the fastest round-trip course and tell you about the pass comes into play.)


So everybody starts to tune his gear because this year the fastest can win:

  • Cool Windsurf accessories from SEVERNE,
  • Premium memberschips from GPS-Speedsurfing.com,
  • Stylish clothing from Fuerte Action
  • and of cause, caps, lenyards and shirts from Dunkerbeck Speed Challenge

Resumen 2017:

Dunkerbeck GPS Speed Challenge 2017

Speeds new guard, dominate in Fuerteventura.

24 year old Dutch speed star Twan Verseput is the new ISWC speed world Champion. Twan together with a huge junior fleet of young talented sailors from around the world, were the stars of the Dunkerbeck GPS speed challenge.

The speed spot in Matas Blancas in the south of Fuerteventura once again delivered a fantastic week with challenging conditions that pushed the 55 strong fleet of men, women and kids to their limit. Conditions varied all week, from riders being maxed out on their smallest 5.0m sails and speed boards to the minimum wind limit slalom baoards and 7.8 m sails.

The surprise upset from the 1st heat was that 42 times world champion and the winner of the last 3 years at this event was not winning!. The young speed star from Holland, Twan was on form from the start. He then went on to win 3 of the 7 heats and 2nd place in all the rest, despite Bjorn using all his experience to fight back. Both he and the Strong man from Sweden, Markus Emanuelsson had to fight all week for the 2nd and 3rd place positions. With Bjorn on the last heat of the week taking 1st place and 2nd overall. As if to make a point, Bjorn achieved the fastest run of the week at 38.66 knots . The new world champion Twan had this to say at the prizegiving at the prestigious R2 Rio Calma hotel  “This is my 2nd time at this event, the Pro Am concept works great here and I would encourage anyone to come. When I was younger I never thought I would be competing with my hero Bjorn Dunkerbeck let alone beat him. I am still in shock“

Dunkerbeck GPS Speed Challenge

The women’s fleet went more according to the form book. With the double world record holder Zara Davis from the United Kingdom winning all of her heats to become World champion for the 2nd year. This was despite strong challenges from her rival from last year Anne Schindler from Germany in 2nd place and attending her first speed event PWA rider Miriam Rasmussen in 3rd place. Zara said on winning her 2nd world title at this spot.“ I was super happy to win here again, the other girls are getting quicker every year and I can’t afford to take any round for granted“

Dunkerbeck GPS Speed Challenge

The truely international fleet of riders from all over the world came together to create a very special vibe. Rivals on the water for sure but they offered support, encouragement and help to each other, to go faster and faster. The real stars of the show was the large youth and junior fleets with entries coming as far away as Canada and the youngest entrant, Ancor Sosa at 9 years old. They all performed brilliantly in some very tough conditions, out pushing hard for a hour at a time in their rounds without stopping. They drew some of the  biggest  smiles from their parents and admiration from the rest of the competitors and public. 1st youth place went to Jonas Thyme from Denmark and the fastest junior Alexa Escherich from Germany.

Dunkerbeck GPS Speed Challenge

The last word must go to Bjorn Dunkerbeck the events founder and last years ISWC World Speed Champion.“ We are very happy with this years event, great vibe 4th time at this site and second time hosting the world championships. Congratulation to Twan, at half my age he just had more speed than me this time. But watch out, I will be back!“
