Posted by Ketch Posts 10 Registered at 2009-10-10 16:57:03	2010-05-01 06:54:41 - 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. Francois

	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... I can replicate (on occasion and always while racing in a top20) interactively, "They won't play if they can't win" - Walt Disney

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

Melbourne to Osaka Prelude 2024

Welcome once again to what these days is Sailonline’s almost annual virtual Melbourne to Osaka Yacht Race. In real life, this double-handed 5500 nm race between these two sister cities, one deep in the southern hemisphere, the other high in the northern hemisphere, is run every four to five years, and is planned to be held again in 2025, so this race is a Prelude in partnership with the Melbourne Osaka Cup 2025 organising committee collaborating with the Ocean Racing Club of Victoria (ORCV), and the Sandringham (SYC) and Osaka Hokko (OHYC) yacht clubs. On this occasion, we’ll be racing the well-known First 40, a popular size of boat for a long-distance double-handed race. With the doldrums unavoidably lying across the track, you can expect to be at virtual sea for at least a month!
