Hi there,
There is an option for that in general config, routes tab (Beep when routing/simp/etc)
Satori is a relative newcomer to SOL and I am documenting what I am learning from generous SOLers. Attached are my introductory instruction notes with screen prints in PDF format for “Editing Route With New Weather Report and Uploading Resulting New Delayed Commands to SOL”.

Hi, Satori, looks interesting. Perhaps simplify the list of DCs by removing unnecessary duplicates? There must be a tool to do that. Also, constantly changing cc's when a single twa will do the trick will be slower, since you take a performance hit every time you change direction. And vice versa, if qtVlm is giving you a straight line and you change twa's to match, it'll be slower. You need to smartly switch between cc's and twa's as the situation dictates. It's the same IRL -- sometimes you go to a waypoint, other times you sail by-the-lee.

Also, on your qtVlm screens, it looks like you're updating a route generated from a previous routing. But with a new weather grid, you may need to rethink your strategy and follow a whole new path. Re-optimizing an old routing is not going to get you what you want, I don't think -- you should start from scratch on each weather update. I suggest setting up a pathway and creating routings from that, especially on long ocean passages. As the race progresses, you can remove early pathway points and use the remaining pathway, starting from the boat.

You'll also find special situations when the race is longer than the grid forecast. Will be useful to have an update on tactics after the upcoming Osaka race.

If you use the new Sailonline iOS client for iPhones/iPads, there are some additional helpful hints. Happy to collaborate.
Also, there's a nice even more introductory intro to qtVlm here: http://solfans.org/blog/routing/qtvlm/introduction-to-qtvlm/
Super writeup Satori. Pivot points figured out from the videos.

Two things. Firstly, I have noticed that Simpilfy/Optimise runs orders of magnitudes fast if the qtVlm window is minimised (on Windows 10), and no graphics updates are happening. Can I make a suggestion that a configuration switch is added to disable graphics updates when Simplification/Optimisation is in progress. I think it will make a huge improvement in performance.

Secondly, I'm running a Dell Displaylink, and qtVlm does not seem to be able to recognise that I have a graphics card loaded. Consequently, all rendering is done in software. Java recognises and uses the card, by qt (C) does not. Any ideas?
Two questions:

1. How do you control level of simplification and optimization? (I've been just stopping them mid process) but are there subtleties and knobs to tune?

2. can you get wind speeds to show up on the arrow points? I found an old photo in Bimmer's thread that had the speeds showing.

TX. in advance as usual!!
In Grib->Grib configuration (or the windsock in the toolbar, or ctrl-G), there's a Label configuration item to show a number.

I don't know that you can control the level of simplification and optimization, other than Optimum/Maximum (the names of my next 2 dogs, and I'll never know which is which).

Abel T Appreciation 2020
In December 1642 after a particularly difficult and rough voyage, the Dutch seafarer and explorer, Abel Tasman, made landfall at a spot he named Staten Landt, believing he had arrived on the coast of Argentina. In fact, he had arrived in modern-day New Zealand. Once again out of love and respect for this brilliant seaman, Sailonline is retracing his route from Tasmania to New Zealand.

The Odyssey 2020 - Leg 1
According to Homer, after the Greeks sacked Troy, one of their heroes, Odysseus, had a particularly fateful journey home. Sailonline now invites you to relive his epic tale, journeying in a virtual ancient trireme, modelled on the Hellenic Navy's real live replica Olympia. The legend tells Odysseus was immediately blown off course, north to the land of the Cicones, perhaps making landfall near Cape Maroneais. When the winds abated and after pillaging the people, he made good progress south, undoubtedly rowing some of the way, to exit the Aegean at Cape Maleas, where this virtual first leg ends. Take your seats for 360nm of tragedy!

San Francisco Bay 2020
Many a Sailonline race has started or finished at San Francisco's Golden Gate, but never have we raced inside The Bridge on The Bay. This 27nm sprint corrects that oversight with a fine sight-seeing tour past Alcatraz, Yerba Buena, Brooks and East Marin Island. Our rarely raced Fox 9.50 is your boat of choice. She's a nippy little thing. Enjoy!

A3 2020 Leg 8 - Darwin to Perth
In 2012 Sailonline lost one of its more remarkable racers, Aaron Gage, the creator of the Flash client and all-round awesome human being. In his memory, Tyger created a superb series of races around the island of Australia - the A3 (Agage's Around Australia) Series. This race is Leg 8 of the series - a race of 1860nm in Orange 125ft Catamarans from the laid back north to the booming mining capital and yachting centre of Perth in the south of the state of Western Australia.
