If you want Qt to row you into the wind, use the attached.

An argument between Poseidon and Aeolus has been resolved and your rowers will now be able to row at near as damn it 2kn, even if Aeolus ins't playing ball and the wind drops to zero. Use the revised polar below if you want to consult the god Qutyvelomis.

Is the AGL working with this? I get an error launching it.

Error interpolating boat polar data.

@Renegade Same here. AGL is stumbling on the polar for some reason. I don't know if Kipper can produce a fix on time. Even a way to switch off the boat polar and just download the WX updates for the grib to be used in routing programs would do for me...

Is the BrainAid polar the same?

I just found a workaround to get AGL to work for downloading the WX updates and for setting DCs.
Here is what to do:
1)In the folder you have set up for this race go to the "SOLGribXml" subdirectory and find the "auth_raceinfo_1388" file there. You can open it in a simple text editor like Notepad.
2)Scroll down in the text until you see this line: "<name>Trireme Olympias v2</name>". All the numbers after that point are the polar data that AGL is failing to read for some reason.
3)Do the same for an earlier race. I used "auth_raceinfo_1386", which was the Darwin to Perth race, but any other race will do. Locate the same boat data in this file, and copy everything starting with "<tws_splined>0 1 2 3 4..." until "</vpp> </boat>".
4)Now paste this data in the file for race 1388, replacing the boat data it failed to use.
5) So what we have done is copy in working, but wrong, polar data to bypass the interpolation error AGL has with the Trireme. Now, save this tweaked "auth_raceinfo_1388" file and start AGL again and it will work normally for pulling in the WX updates or editing your DCs. It will not work for some of the functions that require the correct polar.

Hi Bimmer,
I think Bonk has included the person who created AGL with the observations and questions we had about AGL failure to interpolate the trireme polar chart. I don't know if there has been any answer.

Cross the Convergence 2026 - Sao Tomé to Tristan

The fifth race of our series of ocean voyages across the World’s convergence zones takes us back south down the Atlantic from Sao Tomé on the Equator to Tristan da Cunha on the edge of the Roaring Forties. It’s 2500nm; in your path the Benguela winds and current along the south west African coast, and behind that the St Helena High stretching halfway to South America. So, mind where you go in your Volvo OD65 version 3 (based on sampled real-life race data by kroppyer)!

New Ice Age 2026 - Neumayer Station to Scott Base


For a second-half of long-distance ice-boating, we take our DNs to Antarctica for a circumnavigation of that continent in two legs clockwise, in harmony with the prevailing winds (such as there are), beginning with a race from Germany’s Neumayer Station to New Zealand’s Scott Base. It’s about 3500nm, which, if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you much more than five days. And remember: charts down here are unreliable – what is land and what is ice?!

Viareggio Bastia Viareggio 2026

Our sixth race of nine to celebrate all things Mediterranean - fickle winds, history and olive oil - was planned to be our third buddy-up with another incredible Italian event, the Viareggio Bastia Viareggio (or BVR for short). Unfortunately, in-real-life the BVR has been cancelled this year. But online we shall race it never the less. It’s a quickie – a 160nm roundtrip there-and-back in classic Class 40. Have fun, and if you’re planning a BBQ, piccola isola Capraia halfway across is simply lovely!
