The objective of this project is the development of specialized airborne kites (instead of masts and sails) for boat propulsion in the merchant marine. Our kiteboat 2, a lightweight fiberglass proa 7.3 m long, has been sailed with 2 different sizes of kites in fresh water. The kites are shaped like wings, with areas of 3.7 sq m and 9.3 sq m. The proa is steered with two coupled rudders, one fore and one aft, which worked quite well. We have been encouraged by the obat speed and the handling, although we have encountered only light winds up to now, of no more than about 20 km/hr. In the near future we will receive a custom-built kite of 27.9 sq m, and will also start sailing in the ocean with heavier winds, of about 40 km/hr and higher.
