Multiple routes - how to display all routes offset from start?
Hi folks,
I'm working on routing a passage from Dominican Republic to New York (just in time for the SailGP race ;-) and attempting to use multiple start times, 24h apart. I'd like to then be able to step through the routes but NOT using calendar time, but as steps after the start time. This would overlay all boats on top of each other at the start and visually show how the routes compared.
The behaviour I'm seeing at the moment if that all the boats are shown according to their calendar time, which spaces them out by several hundred miles, and in fact the Optimal/Start button is (thank you tooltip!) actually only the starting time of the LAST routing.
Is this behaviour that can be changed? I've been amazed at all the settings and the herculean efforts it must have taken to build Expedition. Seems like this would be a little setting somewhere that I just haven't found yet? ;-)
Cheers,
greg

It isn't possible - everything is drawn at the display time. In this case, the boat positions are interpolated to the start time, which diplays them correctly with the weather etc.
Thanks. It is an on going effort, although there is a lot of work just to stay still at present.

Re: Multiple routes - how to display all routes offset from start?
Is it possible to display the routings from the beginning of the _first_ routing instead of the beginning of the _last_routing? For a 10 day multi-routing, I cannot see anything from the first 9 days of the sequence at the moment, unless I'm mistaken?
Cheers,
greg

There are buttons on the Optimal ribbon to take you to the start of the routing.
It is also easy if you have the weather for the time period loaded as you can just step through it.
Otherwise, you can specify the display time on the Weather ribbon and step forward or backwards in time.
You can also set the display time from the optimal routing summary.

I think the button labelled "start" on the Optimal ribbon only refers to the start of the last route in the Multiple group. The navigation buttons "start", "previous", "next" only seem to be bound to the timeframe of the last route.
I'll use the weather controls instead.
