Windsurfing mast: sand grains are your worst nightmare

It's one of the worst things that can happen after a long windsurfing session. When the mast gets stuck or blocked by a few grains of sand, you'll know you need to do something before going home.

Many people give up and will keep their giant mast out in the garden. In one piece. Stuck masts can last forever, but they're definitely not portable at all.

Windsurf masts get blocked when they're rigged in the beach, before each windsurfing session. A couple of hours later, when you're tired and surfed out, you've got a problem in your hands. Are you driving with a giant mast on the roof of your car?


Apple iWindsurfer: it didn't had chips or disk drives

In the mid-1980s, and without Steve Jobs in the company, Apple decided to diversify its portfolio of products. A complete windsurfing kit was marketed - with board and sail - but people still preferred computers.

In 1985, an internal battle nearly killed Apple Computer, Inc. Steve Jobs and John Sculley fought for the leadership role, and Jobs was forced to leave the high tech company.

That was when the management team at Apple decided to innovate. The Apple Collection - an odd catalogue of t-shirts, watches, boardshorts, umbrellas, sunglasses, pins, and backpacks - wanted to sell more than just computers. Despite good intentions, it failed.


Dorian van Rijsselberge: master of Rio de Janeiro

Dorian van Rijsselberge and Charline Picon dominated the RS:X races at Aquece Rio International Sailing Regatta 2014, in Pão de Açucar, Rio de Janeiro, Brazil.

Despite the light winds in the test event programme of the Rio 2016 Olympic Games, van Rijsselberge was able to snatch gold in the Men's RS:X by finishing fourth in the medal race.

"It's good for my self-esteem. We've taken in knowledge this whole week, from the wind, the waves, the current and all the little things you need to recognise next time you come back," the Dutchman explains.
