John, I agree with your comments. And yes, you have divined the location precisely, the chart is the correct location.

Here is a screen shot of current wording — see both ‘finish line’ and ‘other’.

I am not sure when the lines referring to the area as an obstruction were added but I think it was done without considering the flow on implications and is not what we are aiming to achieve.

My suggested update will be:
Finish Line

Further thoughts or comments welcome. I have found the discussion very helpful for working through the issue. 

Kevin, Will your viewer eventually be open source?

Many of us download the tracking data from our gps devices into ChartedSails or Njord Analytics for post racing or post training analytics.   There are others that I have not used like Race Vantage and Race Qs.  These are NOT designed for the protest room, although they have much higher fidelity than the Vakaros Player. The advantage however is that they are open source. So if I am training (or racing ) against two competitors with different GPS devices, we can all download our data into ChartedSails and do the analytics. We can input data from Vakaros, Velocitek, Sailmon, Nova sail etc and have all the tracks, headings and detailed data in one place. 

Today, even in club racing, a huge number of boats have a gps device. But it is a free market and different skippers choose the device that most fulfills their need. The ability to have a viewer for protest meetings that is open source and can accept the same data from different devices would be a huge advantage with a wider audience.     

Subject to the same caveats regarding COP and interpolation.   

I see the dropbox in the form for "AI Involvement" now and hadn't noticed it earlier.  Thanks for pointing it out!

See discussion above.

Hitting an anchored boat may found a claim for damages, but does not break any IRPCAS rule.

Hitting a dock or pier, the same.

Clearly placed there by a trimmer trying to share the guilt! ;0))
