This is a line-setting device I fabricated for the recent UK IOM National
Championships, where I was the Race Officer. The idea is that the set of
the start line is taken at an angle of 85 degrees to the incident wind to give
an appropriate line bias at the pin or port end of the start. So the
device features a plastic protractor and a couple of knitting needles tied to
it, with an angle of 85 degrees between the knitting needles. The wind
gauge fits into the top of a wooden handle, and when the tip of the wind gauge
coincides with the forward-pointing needle, the line bias can be set by sighting
the start line buoys along the
other needle.
