My little Wixo digital angle gauge gauge arrived and its arrival set me to work to find out if there was a noticeable difference between a Standard Moses wing angle of attack against my shed built modification, which involved replacing the carbon Moses wing for a indestructible G10 Gong Wing which worked but sailed rather strangely.
After reporting this strange behaviour I found a site which was clearly saying if I was even 1 degree of attack angle out from the correct angle I would be unhappy with its performance.
Well it came as no big surprise to discover my modification was 2.8 degrees out, sitting at 0.4 deg instead of the standard Moses angle of 3.2 degrees.
But after a little bit of shimming work I now have it at 3 degrees.
So now the acid test will be over the next few days, wind forecast is perfect at 15 - 20 mph, sun is out,
air temp Is a refreshing 3c.
Fingers are crossed.
The standard Moses Wing, 3.2 deg
The incorrect angle of 0.4 deg set by eye alone, not the best angle to set for the Gong wing,
At this angle of attack the sailing experience should be much better.
