Re: Routing
I have used Expedition many times and am now trying to set up for the Marblehead Halifax Race. I am able to download a Grib OK, but when I try to optimize I get a message "Unable to sail from start or mark". I have checked all of the times and areas and the grib covers both time and space. Any idea why I would be getting this error?
Thanks

Re: Routing
Do you have:
- a route defined?
- Is the first mark in the route the active mark?
- is there an active polar

Re: Routing
It could also be an avoid land or race note issue.
