Hi maitai,

Thank you for your clarification. I forget that Qt can be used on a phone/tablet. It makes sense to me now the need for "Best performance" mode.
Excellent work.

Please find attached zip which demonstrates the behaviour. The zip file contain two snapshots showing the routing generated from the pathway with the malformed isochrons, and the other directly to the target waypoint. I've also included the grib file and the other files I think you need to reproduce. Please let me know if you need any other data.

Hello,
The problem arises because you ask to route from boat and your first pathway point is already at the boat position. I'll fix that but in the mean time in that case please route from 1st mark in pathway.
There appears to be an issue with the xml header in the GPX export generated by Route Export which I think is causing the strict Java xml parsing to fail. It has to do with the syntax of the version. I've included two sample files of the same route. One that parses, and the other that does not. Is it possible to change the header to suit the version that works? Thanks

OK. Thanks.

Ok, I'll change that
Hi,

In "Boat settings", "Tacks and Gybes";
What does it means "... during __ cranks"?

What is "cranks"?, and how many cranks do you guys usually use?

I tend to set Gybes at "90% of polar speed", but I don't understand how to set the "cranks".

Merci beaucoup,
Antonio
"Crank" is the internal step qtVlm is using. By default it is 5 minutes. You can change that but be sure you know what you are doing ;)

So let's say you don't change the default crank value, if you input 90% for 3 cranks it means the boat will use 90% of the polar for 15 minutes, and most importantly that tacking and gybing again will be forbidden during 15 minutes.
Perfect! Mercy.
Hi Guys,
I've noticed that special characters in waypoint names prevent them from being loaded when sent via NMEA. The waypoint name "Tróia Peninsula" does not load. NMEA sentence copied from qtVlm is below.

$GPWPL,3829.610,N,00854.894,W,Tr�ia Peninsula*F8

Similarly, the attached gpx does not load either. I remove the special characters from Setúbal, Tróia and Póvoa and it all works fine. Both files attached.

Cheers
Andrew

Vuelta de la Isla Saltes Sprint 2025


Welcome to Spain for our first sprint of Q4. This is a traditional 20 NM local race around Huelva in SW Spain. Chances are a quick circumnavigation will involve some upwind work weaving your way round the mud flats of the upper reaches of the Huelva delta in our Fox 9.50. Fair winds!

Camel or Balloon - Khartoum to N'Djamena


As there is a lull in the calendar, your PRO has decided to risk an experiment – a balloon race over land, using a workaround to eliminate the recognition of water/land transitions. If it fails, the server may crash, and we abandon PDQ, hopefully after leg 7 of the ABS race to Suez has been decided, and before the start of the 1st OCC of Q4. Camel or Balloon – c 1000 nm from a field on the north bank of the Blue Nile at Khartoum to a field on the north bank of the Chari River at N'Djamena!

Africa by Sea 2025 - Mogadishu to Suez


Nearly there; only 2500nm to go, round the Horn and up the Red Sea to Suez into what will more than likely be more headwinds for this sixth leg of our African circumnavigation, to be followed in September by a final sneaky dash up the canal back to where we started all those months ago. We’ll be sailing a not entirely appropriate-for-upwind-work 60ft Trimaran!
