Board » Technical Support » Going in the reverse direction?

In the Figaro Transit currently running - I noticed my place had dropped overnight quite dramtically (should have set a CC I thought and OK another major blunder in my course setting - so whats new!). Then I realised I was going backwards at a speed of about .5 knots in exactly the opp direction to the one I had set.

How do I know I didn't set an incorrect course - well its still showing in my course to steer box!

So is this a bug in the system - how is it possible that I am moving in the other direction to the one indicated?

Best wishes

Robert
Mmmm strange. Could you take a screen shot? Looking at your track, it does not look really abnormal.

Hi Incognito

Thanks for getting back - if you track back 46.2 nm's on my current track you will see a weird kink in my course tracker (you do need to zoom in)- this was for a period of I recon three to four hours taking me almost straight head to wind.

No instruction was issued for this indeed quite the oposite.

Best wishes

Robert
i have seen instances of multiple DC's set to fire at the some time that cause TWA=0 responses...

In some polars you can go reverse if using a twa *almost* equal to zero, this is because of the spline interpolation.

Lac Manicouagan Ice Race 2024


Back in 2013, SOLer FR_cirrus introduced us to the meteor-impact crater lake of Manicouagan in northern Quebec province, at 100km diameter the 5th largest such geological feature on the planet. We speculated then that the impact was perhaps the one responsible for the dinosaur extinction, but at 215m years ago that is wrong, and generally that result is attributed to the 65m year old Chicxulub impact on the tip of the Yucatan peninsula. Last time, we raced the 138nm ‘rond la lac’ in Platu 25s, but it’s winter and there’s ice, so let’s take our no-performance-loss so no-holds-barred DNs instead, and get back indoors quickly.
