That's an array 12 ft wide, by 32 ft high, with over 14 sq. m. area, on a boat weighing just 140 lbs.</FONT><FONT FACE="Verdana"><BR clear = "left"> <I>Photo by Jonathan Winters</I></FONT></P> <CENTER> You can search this site! <!-- SiteSearch Google --> <FORM method=GET action="http://www.google.com/search"> <input type=hidden name=ie value=UTF-8> <input type=hidden name=oe value=UTF-8> <TABLE bgcolor="#FFFFFF"><tr><td> <A HREF="http://www.google.com/"> <IMG SRC="http://www.google.com/logos/Logo_40wht.gif" border="0" ALT="Google"></A> </td> <td> <INPUT TYPE=text name=q size=31 maxlength=255 value=""> <INPUT type=submit name=btnG VALUE="Google Search"> <font size=-1> <input type=hidden name=domains value="www.DCSS.org"><br><input type=radio name=sitesearch value=""> World Wide Web <input type=radio name=sitesearch value="www.DCSS.org" checked> www.DCSS.org <br> </font> </td></tr></TABLE> </FORM> <!-- SiteSearch Google --> <BR> <BR> You are the:<BR> <IMG SRC="vcounter.gif" WIDTH="90" HEIGHT="20" ALIGN="BOTTOM" BORDER="0" VSPACE="5"><BR> visitor to this site</FONT> </CENTER> <H3><A HREF="#AYRS"><FONT FACE="Verdana">Amateur Yacht Research Society (AYRS)</FONT></A></H3> <P> <H3><A HREF="../speedweek/WSSR_regs.html"><FONT FACE="Verdana">Speed Sailing Rules and Regulations</FONT></A><FONT FACE="Verdana"> and </FONT><A HREF="../speedweek/FAQs.html"><FONT FACE="Verdana">FAQ's</FONT></A></H3> <P><FONT FACE="Verdana">Everything you ever wanted to know about official WSSR sanctioned speed sailing rules and a comprehensive FAQ (frequently asked questions).</FONT> <H3><FONT FACE="Verdana">Why Kites?</FONT></H3> <P><FONT FACE="Verdana">So, why sail with kites at all?

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.
