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.

2017-04-12 00:08:01 - Malformed Isochrons When Routing From Pathway
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.

2017-04-22 12:32:53 - Java GPX XML Parsing Issue with Route Export
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

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.

2017-08-18 11:03:13 - Problems Special Characters in Waypoint Names
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

Red Eye - Melville Island PYOC 2026

Melville Island is the largest of the Tivi group opposite the port of Darwin in the Timor Sea. Tropically forested and thinly populated, not a lot goes on there, but let’s race around it anyway, lar- or starboard round, it’s a little more than 120nm, so, no matter where you are navigating from on the planet, you will be hard-pressed to complete the course aboard your J-80 in daylight hours!

Iceland to the Falklands 2026

Welcome to an all-new route, the first of three Round the 'Old World' of Europe, Africa, Australia and Asia. To give each leg of the ROW a bit of length we'll try to hug the coasts as little as possible, so starting in Iceland our first leg of the series, which will also be the final leg of our Quarter 1 Ocean Championships takes us 7200nm to the Falklands, the full length of the Atlantic end to end. To make sure we'll get it done within the month we'll be sailing our Maxi Trimaran.
