2016-07-05 09:45:58 - QTVLM Bug Report
How do all

Further to discussions in the RTW chat Odyss pointed out that QT had some annoying bars across the screen. I had initially put it down to a shortage of memory on my computer and the bars being nothing but a drawing issue - but on closer inspection it seems to be affecting the routing - screen shot Odyss posted in chat

Version 5.3.7

The problem occurs when using saildocs and Brainaids gribs

Update- Issue is also occurring in 5.3.5
Update - from Kipper All, just tracked down the Qt bug. If the grib grid resolution is 1 degree or greater, the problem occurs. Of the resolution is less than 1 degree, it goes. I've just reprocessed the Brainaid grib down to 0.5

Hello,
From where is this grib coming from? Is it something generated by SOL somehow?

It is the Brainaid grib and the SailDocs gribs :)

The grib displays fine if the standard interpolation is used.

So it's either inherent to the SOL interpolation formula, or it's a problem in our implementation of it.

Im not a tachie but Kippers point that making the grib denser (to under 0.5)and the problem being resolved seems to suggest its the way QT is handling less dense files.

The conversion is a process few of us (me included!) can do!!

Thank you for looking at this

Kipper has changed the 10:26 grib file into something usefull for QtVlm.
I'll see if I can persuade him to do this to the following updates, until the guys at QT has solved the problem.
They ARE alerted :-)

Another solution is to change the settings in ADVACED fro SOL to Standard.

It looks like there is a transposition error. The stripes are displaced down the page by exactly one grid resolution (2.148 degrees).

Roma per Tutti 2026


Sailonline are honoured and delighted to have been asked to partner an online first Roma per Tutti yacht race with organizing yacht club, Circolo Nautico Riva di Traiano . In real life, this will be the 33rd edition of this 540nm offshore race from Rome’s Riva di Traiano to the Aeolian Islands and back. Online, the race will not only be our first partnership with CN Riva di Traiano, but also the second race of our Magical Mediterranean series. A number of Mini 6.50s have been entered for the 33rd edition of the Roma per Tutti; so our own vintage Mini is also our virtual yacht of choice for this one.

Rommel by Balloon 2026 - Through the Sahara


Generalfeldmarschall Johannes Erwin Eugen Rommel may have been that chivalrous, gallant tank commander of legend, led astray by the Prussian military traditions of loyalty and chain of command, but one thing he wasn’t, was mad. So, let’s do it anyway – not stick to the coast and the battle for logistical superiority – but depart the oases of Siwa south west into the desert for Agadez and its uranium. And let’s go by balloon, it’s only 2500km (1250nm)!
