Posted by Cuccius Posts 3 Registered at 2016-05-15 22:22:28	2016-06-10 07:12:28 - A new command for planning route?
	I am a nembi here so maybe I might tell something you already have an answer for. What I really REALLY would appreciate would be two commands like: 1) take this action when Latitude is => X, or latitude is <= Y. 2) take this action when Longitude is ...... They would be two alternative to the delayed command with time. These two command would make me avoid big headache in computing or imagine where my boat would be in a certain time. Also it would be much more similar to true navigation, because in a true race no one wold decide to tack because the time is 7 past 11. On the contrary one would decide to tack because the 7th parallel has been passed. Thank you so much for your attention best Francom

	This is what schakel did in his program "helm control" (which I can't find right now, maybe he's taken the download offline). The problem with this is how the different commands combine. Right now the commands are ordered simply by their execution time. But when you have commands without execution time, how are they ordered? You will need an additional "number" to specify the order of the lat/lon commands. But how do you combine the order of lat/lon commands with the order of the timed commands? There are multiple sensible answers to all these questions, a choice needs to be made about how to deal with these special cases. Then the server would need to get a large update, and the client needs an even larger update.

	ok I understand the problem. My hypothesis was: I build the route in the order from start to end. So the order of the actions is the order of their creation and the actions could be ordered by creation time. But in this way the modification of a previously planned route would be challenging or maybe impossible. A possibility could be to give together a position condition and a timing condition. If the position condition is not defined, the timing condition is the only valid. If the position condition is defined, then the timing condition is only indicative (it would be actually needed only for ordering purposes).

	Cuccius, Have a look at the DC Checker in this. http://solfans.org/blog/weather/dc-checker-editor-grib-loader-and-more/ It will show you exactly where your boat will be, to within about 5 seconds.

Lake Ontario 300 Challenge 2025

Lake Ontario Offshore Racing (LOOR) welcomes Sailonline sailors (SOLers for short) to a second virtual version of a race in their annual series, the LO300.

Once again, as is our wont on Lake Ontario, a fleet of Beneteau First 36.7s is being made available to virtual racers. There is an overall prize for the SOLer who best bosses Lake Ontario over the two races hosted by Sailonline, this 300 and the Susan Hood raced back in May; so, let the competition be fierce!

Red Eye - Key Lime Pie-gatta 2025

Opposite the Bahamas at the tip of the Florida peninsula, we find the Florida Keys, a honky-tonk arpeggio of islands, where another SOL classic, the Key Lime Pie-gatta, so-called after the famous local condensed-milk-based tart speciality, awaits to be navigated once again. We’ll race its “Red Eye” 180nm in very-American Santa Cruz 52s, ignoring such artefacts as bridges, causeways and piers joining the keys one to the other and to the mainland!

Sail Around Turkey 2025

Welcome to the 11th running of one of Sailonline's most iconic races, where our fleet races the length of the Turkish coastline from Hopa (the easternmost harbour on Turkey’s Black Sea coast) to Iskenderun (the easternmost harbour on Turkey’s Mediterranean coast). It’s a 1,372nm race and aboard our classic, 1st decade of the 21st Century, version 2 IMOCA 60, you should be able to get around the course in less than a week. That is if, of course, once you get out of the Black Sea you don’t stop to enjoy the sights or a BBQ or two in the Golden Horn, or on the Marble Islands, now land-locked Troy or Gallipoli or any of the myriad Aegean islands, that you shall have to carefully navigate past.
