GSHHS High Resolution Source - ZyGrib?

Stelian... What I see on your picture seems definitely a WR/step issue and an understandable one. If the end point is reachable over water at all, the last isochrone legs over land should be ignored and step decreased to find the way to the finish.

Agreed, we've been talking about doing this and Sean thinks it would be a good thing to do. -Automatically adjust the intervals to successfully complete.

On Rick's picture it seems like several legs were computed on land, that sure should never happen. Pavel

Yes, I was surprised, but now it seems to be fixed, now that I have not "touched" or messed with what ChartDownloader does with GSHHG.

Thanks for bearing with me on this.
