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.

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!
