The operation of the towing kite


The SKS-Y-System comprises three main elements:

  • A kite wing with its towing rope
  • A launch and recovery system
  • A control system for automatic operation

Instead of a traditional sail fitted to a mast, SkySails uses large towing kites to propel the yacht forward. Their shape is similar to that of a paraglider. The towing kite is made from high-strength, waterproof fabrics.

SkySails can operate at an altitude of 100 to 300m, where stronger, more stable winds prevail. The tractive forces are transmitted to the yacht via a line made of very high-strength synthetic fibres.

The launch and recovery system is installed on the foredeck and it manages the lowering and deployment of the kite wing. During launch, a telescopic mast unfolds the kite wing whilst lifting it. Once it is at a suitable altitude, the wing unfurls completely and can be launched. A winch releases the towing rope until operating altitude has been reached. The recovery process is performed in reverse order.

The launch and recovery procedures each take a total of 10 to 20 minutes.
