Great guys :-) but what about the port for brainaids NMEA proxy? It's automatically set to 5010, but I'm shure I cant use the same port if I have 2 or 3 races to run simultaniously, or what?

Viva all.

Installed the new qT version (5.3.9) and the only big difference I’ve noticed was the Polar display bug that was solved.

Still remaining the old problems of:

1 - Over decimating waypoints during the “Simplifying” process;
2 - Increased ETA after the “Simplifying” process;
3 - Idem, after “Optimizing”;
4 - Tacks/gybes times under the specified times in the “Boat settings” menu.

There’s no other way to say it.
Again frustrating, because it takes almost the same time as the routing calculation to correct all the bad “curves” generated after the “Simpl./Opt” processes.

I'm trying to understand what 'simplifying' means. If it's deleting poi's that are within a certain margin not leading to a different heading then indicated by the surrounding poi's then this simplifying would just cause less poi's. This is not the same as a decreased ETA. If you then optimize these simplified poi's series I can imagine that this optimization of 'errors' brought in by the simplification again can do unexpected things with ETA.

Why would you try to 'simplify' JB.
Could you not first 'optimize' and then 'simplify' the exported csv by yourself?
deleting same TWA's and or same headings?

I'm trying to get a better understanding of what a router does. Hence these questions.

Simplifying has 2 modes: optimum and maximum. Optimum keeps more points and is slower to run. Maximum will try hard to remove a maximum number of points. Maximum mode might even increase slightly ETA.

If "optimum" looses time (ETA) then it's a bug. Please provide necessary information to fix it since I didn't succeed to reproduce it.

Also explain and provide examples for the "time to tack" issue your are mentioning.

Beware a new qtVlm version is due in the coming days. To avoid frustration again better provide some more info on existing problems, or they will stay as they are once more ;)

Sinbad by Balloon 2025 - Baia de l'Oiseau to Carnarvon


How ever shall I return to report with clear report to the Sultan – asked Sinbad. It must be told this island and all its fables shall be expunged from the annals of every thousand and one night. The wind howls here, and sun be none (it’s Winter, Sin, ed.) and all days from the west, but let’s launch anyway and see if we can work our SOL Balloon north as the days pass aiming for Asthralaya, where The Mahabharata tells the ancients once tested mighty weapons, about a quarter and a million qasbah away (2500nm, ed.), perhaps one month.

Nantucket Sprint 2025


Welcome to Nantucket, from whence Herman Melville’s Cap’n Ahab sailed round The Horn into the northern Pacific Ocean to hunt the gray whale - whose migrations are celebrated elsewhere in SOL’s Q4 schedule - he never to return. And whaling too, as the 19th C progressed, like Ahab disappeared from Nantucket as the harbour silted up and mainland Massachusetts whaling stations benefited from rail connections. But beach life, yachting and nostalgia has rescued the island from oblivion, so to celebrate leisure, SOL gives you the Nantucket Sprint - 25nm in 29er_XX’s from Great Point to Muskeget & Tuckernuck Islands across the sound to a finish just inside the mouth of the harbour. Enjoy!
