The prices of the Kite-Boat and the SkySails systems are almost similar to a complete performance rigg (including sails, all winches, rails, blocks, ropes, mast, boom, stays and all other parts and reinforcements required for a standard rigg) but Kite-Boat and SkySails systems come with the big advantages of a kite:
- does not create any shade on the solar panels, which doubles the energy production per day.
- has a much higher performance than a sail on courses from 90 – 180 °.
- significantly less and lower cost maintenance than sails
- safer, quieter, up-to-date technology
The KiteBoat system is available for the SILENT55, which has the sail option too. The Kite-Boat and SkySails systems are both available for SILENT 80.
