Everything you ever wanted to know about official WSSR sanctioned speed sailing rules and a comprehensive FAQ (frequently asked questions).
So, why sail with kites at all? And particularly, why use them for high speed sailing? Here's the scoop.
Here's a bunch
of photos, both of boats I've designed/built and
of kites I've flown over the years. (Yes, many photos are in black and white, do
not adjust your set.)
Arnulf Refsnes' kite launching system, with some prior art on the mechanism. Also, a link to his new website: http://www.marina.unit.no/~arnulf/prosjekt/theproject.htm
My first/last hydrofoil speedboat. This Greg Ketterman/Dave Culp collaboration "flies" on a single foil, and is designed to achieve three-axis stability through Trifoiler-like surface sensors. Dubbed "One Oar in the Water" by her crew.
Here's a collage of big boats from the 1980's; Crossbow I, Crossbow II and Slingshot. This was what it took to go really fast, before we learned from the boardsailors that "less is more."
Here's a brand new, profusely cross referenced paper collaboratively written by 7 kiting, sailing, and aerodynamics authors. It is expressly concerned with using very large kites to pull ocean going ships. A version was first presented before the World Aviation Congress at the Sheraton Gateway Hotel, Los Angeles, California, on October 24, 1996. Sponsored by SAE Aeorspace and AIAA.
This study summarizes the current status of sail assisted commercial steamships, the industry's strengths and weaknesses, and why it isn't widespread today. Ways in which free flying kites used in place of conventional sail may ameliorate some of these negatives, while incurring new problems, is examined. The specific advantages and limitations of crewed and self-sufficient KiteTugs, a new class of lighter than air sailing vessel/sail assist device are investigated. A detailed breakdown of potential KiteTug cash flows and cost-effectiveness is included.
This is an article I co-wrote with Billy Roeseler, now of Kiteski®, and delivered at the Proceedings of the Eighteenth Annual Conference on Sailing Technology (formerly titled "The Ancient Interface"), Sponsored by The American Institute of Aeronautics andAstronautics, (AIAA), San Francisco Section, and the Socient of Naval Architects and Marine Engineers, (SNAME), Northern California Section, Volume 35. We presented it at Stanford University on October 14-15, 1989.
