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).

Red Eye - Myth of Malham 2025

In 1947, Hugh McLean & Sons of Gourock, Scotland built a radical racing yacht for John Illingworth, soon-to-be Commodore of the RORC, to a design by Laurent Giles. With a masthead rig, giving her ‘free’ sail area per the rules of the time, and short overhangs reducing pitching, Myth of Malham went on to win The Fastnet that year and again in 1949, and to compete in numerous Admiral's Cups. In 1958, in honour of the yacht, the Myth of Malham race was conceived - a mini-Fastnet to the first lighthouse on a rock west of Cowes, Eddystone, rather than the second, to be held in non-Fastnet years. IRL this year it has been raced already, but this stops us not from “Red Eye” racing its online 230nm in Fareast 31Rs, leaving how to deal with the Isle of Wight open to your own discretion.

Africa by Sea 2025 - Maputo to Mogadishu


The fifth leg of our exploration of Africa By Sea takes us north along the length of the Continent’s succulent sub-tropical and tropical Indian Ocean coast. Much fought over by traders and colonists both well-before and after a Portuguese expedition under the command of Vasco da Gama first sailed there from Europe back in the 16th century, it is yet to be properly explored as a yachting destination. With plenty of islands off- and inshore, small and very large, there is much to interrupt your 1900nm voyage and visit in your Swan 65, from Maputo to Mogadishu! Race #1858
