Simon Sivertsen, a young inventor from Norway, has developed a wing that will change the way we explore the underwater world.

Sometimes, you just need a trigger to come up with a great idea. While attempting a circumnavigation around the globe with his father, Simon had a vision in the heart of the Mediterranean Sea.

"When sailing through the Greek Islands, I was astounded by the clarity of the water, it almost felt like flying when diving, just missing the speed and thrill. The first ideas of an underwater wing, towed behind a boat, started emerging deep in the right hemisphere of my brain," explained Sivertsen.

"A piece of driftwood was perfectly suited for a first simple test of the concept. A waterski rope was attached to the plank and pulled by our small rigid-inflatable boat. The idea worked, and I was able to control the up/downward moment without too much effort. But it was far from perfect."

The product evolved in Simon's brain and quickly transformed into a first prototype. Later, and after a lot of testings, the young entrepreneur completed a final version of his underwater wing. He called it Subwing.

The Subwing consists of two separate wings connected by a rotatable swivel. It can be easily controlled in all directions by grabbing the grip on each wing. Maneuvering is done by tilting the wings in different angels. Tilt both wings downwards to dive, and upwards to resurface.

Simon Sivertsen says it's quite easy to control the Subwing and, because water is about 800 times denser than air, you can rapidly feel the adrenaline pumping through your veins at a towing speed of around two-to-four knots.
