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

Cross the Convergence 2026 - Samoa to Hawaii


The second race of our new series of ocean voyages across the World’s convergence zones, takes us northward again up the Pacific Ocean, now from Samoa at 13.5 degrees South, across the Equator to Hawaii, famed for its breaking surf and active volcanoes, on the edge of the Tropic of Cancer at 19.5 degrees North. It’s 2300nm, so we’ll take our very steady Steinlager II. Race #1982

Beketov by Balloon 2026 - In Siberia


Way-back-when France and England, and Spain as well, were squabbling about who should control what of North America, only to lose the most of it to their own insurging colonists, their eastern European neighbour empire, Russia, was quietly assimilating vast, thinly nomadically populated territory of its own – Siberia! Amongst the many explorers and adventurers that served Russia so well in these conquests was the Cossack hetman Pyotr Beketov. Let’s pretend we’re he and eschewing horseback, let’s travel by balloon from Yekaterinberg to Krasnoyarsk – just a short 2000km (1100nm) section of the Trans-Siberian Express’ 9289km!

West Papua to Oregon 2026

Our next race in our Ocean Championships is the first of a series of great natural migrations we will track in 2026. The leatherback turtle is the most widely distributed marine reptile on planet Earth, and chooses to breed in warm tropical waters, but prefers to forage in more temperate habitats, travelling thousands and thousands of miles effortlessly annually to maintain this way of life. Our race will follow one of the typical trips of this turtle, from breeding grounds in the seas off West Papua to the coast of Oregon. It’s only 5900nm, so to keep up, but in comfort, we’ll follow in our Gunboat 90.

A-OI!!! The fiery spirit of Shetland’s legendary Up Helly Aa returns, and Sailonline’s annual race to Lerwick is once again upon us. Covering 383 nautical miles from Aberdeen, SOLers will tackle winter waters steeped in Viking tradition. This year, we race the classic Frers 33, a proven cruiser-racer born from the golden era of offshore racing and still a sturdy performer both on the virtual and real water. Can you master the course and reach Lerwick in time for the flames?
