Board » Technical Discussion » 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

Poll: would you like a command that make you take an action on certain latitude or longitude ?

sorry for the misspelling of some english.
I am a newbe, not a nembi.

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.

It will show you exactly where your boat will be, to within about 5 seconds.

New Ice Age 2026 - Browerville to Longyearbyen


Our 2026 long-distance ice-boating challenge continues with a second race in Arctic waters, now from Browerville, where we arrived less than a month ago, continuing east, back to Svalbard’s Longyearbyen, leaving Canada’s Ellesmere Island to port and Denmark’s Greenland to starboard. It’s about 2500nm, which, if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you more than a day or three, thus to complete your first (of several) online circumnavigation of the planet of 2026!

Cross the Convergence 2026 - Samoa to Hawaii


The second race of our new series of ocean voyages across the World’s convergence zones, takes us northward again up the Pacific Ocean, now from Samoa at 13.5 degrees South, across the Equator to Hawaii, famed for its breaking surf and active volcanoes, on the edge of the Tropic of Cancer at 19.5 degrees North. It’s 2300nm, so we’ll take our very steady Steinlager II. Race #1982

Beketov by Balloon 2026 - In Siberia


Way-back-when France and England, and Spain as well, were squabbling about who should control what of North America, only to lose the most of it to their own insurging colonists, their eastern European neighbour empire, Russia, was quietly assimilating vast, thinly nomadically populated territory of its own – Siberia! Amongst the many explorers and adventurers that served Russia so well in these conquests was the Cossack hetman Pyotr Beketov. Let’s pretend we’re he and eschewing horseback, let’s travel by balloon from Yekaterinberg to Krasnoyarsk – just a short 2000km (1100nm) section of the Trans-Siberian Express’ 9289km!

West Papua to Oregon 2026

Our next race in our Ocean Championships is the first of a series of great natural migrations we will track in 2026. The leatherback turtle is the most widely distributed marine reptile on planet Earth, and chooses to breed in warm tropical waters, but prefers to forage in more temperate habitats, travelling thousands and thousands of miles effortlessly annually to maintain this way of life. Our race will follow one of the typical trips of this turtle, from breeding grounds in the seas off West Papua to the coast of Oregon. It’s only 5900nm, so to keep up, but in comfort, we’ll follow in our Gunboat 90.
