		<title>America&#8217;s Cup</title>
		<description><![CDATA[For any of you following the lead up to the American&#8217;s Cup Deed of Gift (DoG) match race to be held in early February, you&#8217;re probably familiar with BMW Oracle&#8217;s entry into the match as the Challenger of Record, a boat some are calling DoGzilla. Below is a picture of the boat from yachtpals.com showing [...]]]></description>

		<title>The Amazing Work of Hanno Smits</title>
		<description><![CDATA[Just after I posted the multihull link I remembered intending to show you a hydrofoil sailboat prototype incorporating one of the same principles as Radboat, namely something similar to what I call aeroballast. I ran across this link about Hanno Smits on Monday of this week. Oddly enough in all the research I performed leading [...]]]></description>

		<title>Large Multihulls</title>
		<description><![CDATA[Not any real news to report, so why not share a great link from Yachtpals that does a great job compiling information about some of the coolest and most advanced multihulls, some of which are described on my Exotic Sailboats page. It even has a great video. Here you go. http://yachtpals.com/monster-multihulls-9004.

		<title>Patent Update</title>
		<description><![CDATA[At the request of a great friend to whom I owe my sailing knowledge and skill, and who calls me ALL CAPS, I&#8217;ve made a PDF version of the patent and shared it here. I plan to follow this up with a bit of condensed and clarified explanation. For those that have read, written, or [...]]]></description>

		<title>Speed Sailing Updates</title>
		<description><![CDATA[Let&#8217;s start out with a &#8220;good&#8221; YouTube video of a windsurfer on a speed run. Note the lack of annoying music and credits and the short viewing time. Just a great video showing how ridiculously fast these guys can move.

In the meantime l’Hydroptère broke both the 500 Meter and Nautical Mile Records, and Banque Populaire [...]]]></description>

		<title>Pivot Assembly Prototype</title>
		<description><![CDATA[Currently working on the pivot assembly prototype. I decided to use a 1/2 inch PVC &#8220;T&#8221; fitting for the relative wind pivot, which allows the sail to lean into the wind. I&#8217;ll provide better explanation of the pivot assembly in a future post.

		<title>Apparent Wind Angle &amp; Congratulations Greenbird</title>
		<description><![CDATA[
In their latest News posting for April 1, 2009, the Wotrocket team point out that they&#8217;ve installed a &#8220;new Nexus instrument package&#8230;including a wind wand on the leading edge of the wing sail that gathers data which allows the co-pilot to trim to the apparent wind angle.&#8221; It&#8217;s worth mentioning here because trimming to apparent [...]]]></description>

		<title>Design Approach</title>
		<description><![CDATA[In the post entitled &#8221;Beyond 50&#8220;, Bob Imhoff shares his insight about &#8220;barriers&#8221; to high speed sailing. I&#8217;d like to discuss one of these barriers myself, drag.
In aeronautical engineering drag is a funny beast. The slightest bump, seam, or protuberance can cause seemingly disporoportionate amounts of associated drag. The goal, therefore, lies in designing and manufacturing aircraft [...]]]></description>
