It is a predicted time based on the wind, your polars etc so you do need wind.

Matt,
You can do pretty much what you want already.
Use todays wind (You're going to ignore it anyway)
For departure time use todays tide equivalent to the tide you want to leave on (If you want to leave at 0600 on July 1st; see what that tide is, say 1 hour before high, and find that tide for today and set that as your departure time)
Then set your Opt Advanced/Minimum sailing speed highte than your highest polar speed (this will assure you always motor)
You'll get an all motor estimate with waypoints and if you enter Opt Advanced/Fuel rate, you'll get how much fuel you'll need in liters.
We do it for deliveries and it works pretty good!
Cheers,
Ernie

Hi thanks, yes this works with Optimal tooltip, but I was hoping could get ETA in "Route" window to update for marks.   I export Optimal route as .gpx, and set active but route ETA for each waypoint is still current time. 
Unless II am missing something?


Thanks

Hi,

I did export the optimal route as a .gpx , then imported as .gpx , set as active route.
However for me, with gps as only nmea input, on the route tab, the eta is still current time.   I can view predicted times in optimal > results,  but I wanted to see in the route tab

Yes import to same pc or use the save to marks - either way when set that optimised route active, and from window -> route tab, the waypoints are not showing a valid ETA - as I have no wind data input.   I am using the laptop with expedition as the primary chart plotter as well, and as vessel am on has no wind instruments, only have COG/SOG to plan and play with.

Is more for rest of crew to easily view the ETA easily when on watch, as opposed to having to manually calculate or use tooltip on the optimal route to get an eta.   For now I am just moving mouse to waypoint and get distance/time from status bar.
