Suggestions for the salty links (found in VORG Tutorial v2.05i April 2009):

• MarineWaypoints.com, Great Circle Distance Calculator: to calculate shortest straight line between two points on sphere (http://www.marinewaypoints.com/learn/greatcircle.shtml), very easy to use.
• Time to Wind Change Calculator excel file, can be downloaded from www.bigamistonline.com/onlinefiles/VOR70GameB.xls.
• On-screen ruler, http://www.markus-bader.de/MB-Ruler/download.d.htm. It is transparent, (1) superimpose over map, (2) calibrate, (3) place origin on first point using drag-and-drop, (4) place on second point to display distance, (5) double click on centre circle to hide ruler for later.
• Virtual regatta routing planner tool combing accurate high res weather forecasts with intuitive easy to use interface: VRTool version written with the VORG in mind, http://www.tecepe.com.br/nav/vrtool/.
