  The use of inflated sails for ship propulsion.
  Abstract
  Elevated sails or (kites) have been used by a number of proponents of this technique on vessels ranging from outright speed vessels to commercial displacement vessels, mainly as research projects.
  The purpose of this paper is to discuss the author's practical experience gathered over the last 9 years and then to detail some of the possibilities that are being created by new materials and heat sealing technology that he is presently applying to both elevated and non elevated inflated sails. Included are wing sails and vertical sails (which do not necessarily need masts) and can be warped to achieve the desired direction of travel, as well as inflated magnus effect rotors.

• Early European kiteskiers were Keith Stewart and Theo Schmidt (AWEIA member.  http://www.dcss.org/speedsl/ST89refs.html   http://www.ihpva.org/HParchive/PDF/hp51-2001.pdf ) , who also was among the first to waterski with kites. American Cory Roeseler together with his father William developed a Kiteski system for waterskiing and began winning in windsurf races featuring high following winds, such as in the gorge of the Columbia river.
