Rising fuel prices have shipping companies scrambling for ways to cut costs. Many have opted for more fuel-efficient engines, but now there's another solution. For a decade engineers in Wismar have been developing a sail for freighters. Like a kite, it soars in front of the ship, reducing fuel consumption by as much as 50%. The Skysail costs 400,000 euros, but should pay for itself in three years. Beluga Shipping of Bremen helped with the product's development and is the first company to use the new sail. We accompanied the crew to Venezuela on the Skysail's maiden voyage.
