Maybe I'm thick but I cannot see how to create a route / manual or auto, in Navionics and assign a starting date and time to it.

I don't think you can 
However, the only time I could think that would be useful is if you expected it use tidal information. When I looked at a couple of routes I'd planned the in the App, it had ignored the tidal flows completely and calculated the travel time as distance / boat speed. The only thing it did appear to take notice of depth, though as I recall that didn't stop it charting a course directly over a navigational hazard.

Hi yes that’s exactly what I was wanting it to do. It has the right info ref tidal flows and heights and it seems to know when tidal height makes a section of route risky.
Navionics seems an odd mix of great and weak. Not helped by the fact it is not supported on my Garmin plotter.

I have not been using Navionics long, but have found one should be wary of using the Autoroute function. It may choose a strange route and even when it goes the right way it puts in a vast number of waypoints. Easier by far to do it manually. AFAIK it has no ability to use tide planning.

Yes I wasn't really meaning the Autoroute feature. Too easy to rely on it. Also doesn't make you look at every setup of your route properly so its easy to miss something important.

Another unsafe quirk of Navionics is that, if you have a tidal station open, all charted depths change from datum to the depth at the state of tide displayed.

Oh, really I hadn't spotted that.

Crikey!! I was quite unaware of that.
Seems like a dangerous “feature”.
Will watch out for that in future.

I've just tested this, can confirm that is indeed the case. You have to have the tidal feature selected (get the HOT and tidal curve in the bottom of the display). Only applies to the mobile versions, the online web does not offer support for tides tides.
Now I know it's there that's (maybe) quite helpful. It's "time right now" of course so useless for planning.

Unless of course you swipe your finger left or right on the tidal curve to change the time.

Two years later, yes that's right. I know a lot more about Navionics now and have also just bought the Navionics chip for my new plotter.

Ha! Only just seen the date, sorry Scala. Only got Navionics on the tablet this morning and stumbled on the tidal time shift thing by accident before searching for tips on what the heck it does and does not do.

No worries I do like Navionics and the easy integration between phone, tablet, boat chartplottter, and web browser. But like all charts and charting tech you need to treat it as a guide not gospel.

Yup. Thought it would be useful to have it on a tablet at the chart table that links with the Vulcan 12 topside that uses the same charts on a card. Now I just need to learn how the make the most of them both. Still like paper all the same...

You can spend many an idle hour at your desk whilst you're "working" by planning passages and routes using the Navionics web app on your computer... save teh ones you like and they'll sync to your tablet and plotter
