		<description><![CDATA[Hi, I&#8217;m going to give the concept of Velocity Made Course, or VMC in short, another look. Hopefully easier to understand, let&#8217;s go. Why? With routing, we are dealing with three issues. 1. Wind changes over time. Here VMC gives the perfect solution. 2. Wind is different in space. Think weather map. VMC is sorta &#8230; <a href="http://solfans.org/blog/sailing-by-the-numbers/vmc-revisited/" class="more-link">Continue reading <span class="screen-reader-text">VMC revisited</span> <span class="meta-nav">&#8594;</span></a>]]></description>

		<description><![CDATA[The Hawaiian ZigZag race is a personal favorite for me.  It&#8217;s a long sprint through warm waters that bring back great memories.  This year, I was excited to test the Delay Command Checker software (DCC) during the race.

A race that just has everything that SOL has on offer for the (seriously?) ‘serious’ on-line yacht racer, including in this case: the wind puzzles of the Black Sea, the hunt for balance between angle and pressure in the Etesian winds of the Aegean, a big ask on boat-handling skills &#8230; <a href="http://solfans.org/blog/routing/qtvlm/turkey-time/" class="more-link">Continue reading <span class="screen-reader-text">Turkey Time !</span> <span class="meta-nav">&#8594;</span></a>]]></description>

		<description><![CDATA[Here is one more example to illustrate VMC, and how targets change. We start with a cyclone. A perfectly well behaved cyclone. The storm just sits in place and maintains it&#8217;s strength. It&#8217;s not even that unrealistic, the tropical storm near Madagascar in SWR Leg 2 behaved like this, as do coastal effects.

		<description><![CDATA[In the last chapter I&#8217;ve explained my approach to VMC-sailing, now let&#8217;s poke some holes into it. I do believe that a constant VMC target is the optimum solution for wind changing over time. That however leaves one mortal flaw: wind changes over space!
