I have developed a New Free WebApp tool to help race officers set up the marks for yacht races. You simply enter the wind direction and the windward leg length, and the tool provides the bearings and back- bearings for all Marks => for Both Triangle and Trapezoid courses. Another option provides lat/longs for all Marks after the user clicks a Geolocation button at the bottom mark as the reference point. No more fiddly tables.
I would like to get some feed-back on it.
See www.setcourses.com
