Navionics & Garmin part 1, long live Plotter Sync

Did my planned back-to-back reviews of evolving Navionics and Garmin apps suddenly become moot when the Garmin acquired Navionics on Friday? I don't think so! The terrific Plotter Sync integration I've been experiencing between the Navionics Boating app and multifunction displays from Simrad and Raymarine is not likely to go away anytime soon, if ever, and it may add significantly to your current navigation happiness. Moreover, many Garmin owners are about to receive a wonderful app gift, and while the different advances are not such a competition now, together they suggest the broad harmony between phones, tablets, PCs and MFDs many of us will eventually experience on our boats...

These entries will also be a chance for me to preach about using routes to avoid navigation mistakes. I know that many experienced boaters understand their value, but the multifunction displays that otherwise deserve their popularity do not yet shine at route making, and these days many of us simply don't do what our screens don't make it easy to do.

For example, the AIS track above shows a very well equipped and operated yacht that almost got to Philadelphia before realizing they'd missed the C&D canal. Now, they were never in danger because they were still navigating an elaborately marked commercial channel, but even a crude route showing the major turns on their chart screen could have prevented what must have been a "holy s..t" moment toward the end of a long dark night.

I've certainly had such moments myself, and this case of navigating to the wrong side of Cape Cod in a gale is perhaps especially interesting because I thought I was on a safe route. Creating, checking, and using a route to the next destination is a great start at good situational awareness, but a wise navigator regularly uses all resources available to check on their situation. In fact, one lesson of that terrifying moment off Cape Cod is that a wise navigator is slightly paranoid, as in "Sure, everything looks good, but what am I missing?"

At any rate, the Plotter Sync route transfer feature of the Navionics Boating app has been an excellent tool as I first moved Gizmo at delivery pace from Maine to Annapolis (discussed here) and then slow cruised/tested down Chesapeake Bay to Hampton (tracked here). A major reason is the superb Dock-to-dock Autorouting I deep reviewed in late 2015. It seems even better now, and far ahead of other autorouting software I've tried, even including the same Dock-to-dock algorithms adapted to an MFD (at least currently).

But I want my routes on a dedicated, bright marine display where I can use them with radar, sonar, autopilot, whatever chart type I want and more. And while the Navionics app has long claimed limited plotter sync, the big news today is how much they've improved the feature. In fact -- I like to think that going to extremes is one way I can help boaters with many different systems and/or preferences -- I've now got Plotter Sync working with Simrad and Raymarine MFDs (above) using Dock-to-dock auto routes created and edited on an iPad, an Android phone, or on a PC (using Navionics free web charts), and I've also been able to import them into other charting apps on various platforms.

So let's detail the process I often use, building routes on my iPad and then syncing them for use on Gizmo's Simrad NSS evo2 displays. While sitting on Gizmo in the intriquing fishing village of Reedville (above), at rest with main navigation systems shut down, I was thinking about various harbors I could visit next. In less familiar waters like the Chesapeake -- I've been here often over the decades, but there's so much to savor -- I'm often aided by printed guides, ActiveCaptain, and sites like Google Maps, Yelp, and so forth.

Getting a route to one possibility with total distance and time (at an average speed I've already set) takes three finger taps -- invoke autorouting, start here, end there -- along with a little zooming in/out, and a few seconds of processing. I check the routes at high zoom and sometimes add manual waypoints, also easy and fast, but usually they're quite sensible and they honor buoyed channels while also highlighting possible issues of depth, bridge heights, etc.

I also try to give the routes useful names, because those names nicely transfer everywhere in the Sync universe. (But I've now learned that long names don't necessarily transfer in full and that many special characters, like the apostrophe in "Rville-Gwynn's" can break a route on another platform.)

Now comes the Sync. Navionics has made it easier to understand how it's done, as seen in my opening image, and also easier to see that it's worked, seen above. First you log the mobile device running the Boating app onto the MFD WiFi, and, after a pause, you will hopefully see that your routes and markers (waypoints) have transferred. But there's one more step, and first some notes are warranted:

* You'll see the warning on the larger righthand screen that, "Something went wrong with your last sync," but the only thing 'wrong' was that the card in slot 1 is not a Navionics card. Pop the non-Navionics card and the warning goes away, as seen inset.

* According to Navionics' Plotter Sync page, "Active subscriptions are required on both the plotter card and the app," but I've seen routes transfer to a 5-year-old Navionics card that hasn't had an active subscription since and Navionics has confirmed that I'm not confused: "Plotter Sync requires active subscriptions on both mobile and plotter only to update charts; Routes and Markers sync as long as the mobile subscription is active."

* If you check out the current version of Navionics' thorough-seeming Compatability Guide (PDF here), you'll see that NSS evo2 is not supposed to support Plotter Sync. But it does, as seen above, and Navionics again confirmed: "You are right and we are amending the guide. Navico units with WiFi or even with the external WiFi-1 can do Plotter Sync. There is one exception -- the Lowrance HDS Gen1." But if you check out this recent Forum entry, you'll see that one techy B&G Zeus2 owner can't get Plotter Sync to work.

So there may be glitches, good and bad, but consider the challenge Navionics has tackled. As a whole passel of compatibility guides suggest, they're developing apps on all the big, fast-changing, and uncaring platforms -- while the Boating app is iOS and Android only, the PC Chart Installer program and the browser app Chart Viewer are certainly part of the overall system -- while also trying to integrate with all sorts of MFD operating systems belonging to marine electronics companies that may care too much about what Navionics is up to.

I don't know if the last step in getting Navionics Boating routes to work on your plotter is a technical necessity or a mandate by the MFD manufacturers, but some boaters will find it annoying, at least at first. The routes and markers are synced to the Navionics card in the MFD, not to the MFD's own route and marker database. So what I'm doing on the Simrad NSS7 evo2 screens above is using the Files menu to find the Archive/Routes folder on the Navionics card where I can then import them into evo2.

Navionics explains the Simrad sync process here, where you'll also see that copying routes and markers from the MFD to the Navionics app requires a similar intermediary step in which the data is saved as a .gpx file to the Navionics card first. Either way is a little awkward, for sure -- especially compared to the Garmin Bluechart Mobile sync style I've enjoyed since 2013, with which an app-created route can become the active MFD route in one step -- but bear with me for the positives.

Once imported into the Simrad NSS, the routes appear in the plotter's routes list with the same Navionics names (though maybe shortened), and that's not true with the current Bluechart Mobile sync. With Navionics you can also transfer many routes at once, even use the "All_Routes.gpx" file you'll find in the Archive folder to import them all at once. And the same is true of Markers, which could be a major boon to the fishermen who use them extensively. Be aware, for instance, that routes and marks synced to your MFD, or vice versa, are then backed up on your mobile and also to Navionics's cloud if you've allowed this other form of sync in the app. But I get ahead of myself.

Going back to my recent personal routing process, note above that I can activate a NSS route either from the list or by tapping on the route overlaid on the chart. And then...

...Ta-dah! The NSS7 is ready to guide me along with Course to Steer (CTS) to each succeeding waypoint along the route -- distance to waypoint, cross track error, and more are also available, just not shown here. Total Distance to Destination (DTD) can also be shown and the Estimated Time of Arrival (ETA) at destination or next waypoint (ETW), as well as times to destination or waypoint (TTD or TTW), will all be calculated as soon as I get moving and will respond to changes in current, course or speed. And the route I could have made at home or anywhere will be active on the NSS14 on the flybridge when I get up there, with numerous alternate routes ready to activate because the whole process is actually pretty easy once you get used to it.

I'll add that I often deviate from routes, sometime due to changing conditions, sometime just for fun. The go-most-anywhere freedom of boating is too glorious to get overly rigid about a plan in my view, but having a route at hand is at least a good reference to what you figured to be a safe plan when focused on the subject. And you probably won't miss a big turn into a canal in the middle of the night, or similar, or worse.

Sync on Raymarine

The process of using Navionics Plotter Sync with Gizmo's test Raymarine eS128 is very similar to the Simrad routine -- Navionics how-to page here -- but there's another reason not to spend much time discussing it. Plotter Sync currently does not work on the Axiom series running Lighthouse 3, but it's scheduled to fairly soon, and maybe at about the same time that the much improved LH3 interface comes to older Raymarine MFDs like the eS128. In other words, Raymarine owners may see the best Plotter Sync implementation yet, eventually.

But couldn't Garmin's acquisition of Navionics change this situation? Again, I don't think so, at least not quickly. Why would Garmin give up Navionics chart revenues, and isn't Raymarine's main business hardware anyway? Heck, I wouldn't be surprised if Garmin soon announces MFD support for the FLIR/Raymarine M200 thermal camera I'm finding so useful. This business is complicated. Then again, Raymarine has long supported C-Map cartography, Lighthouse 3 recently included, and the Navionics loss of independence may be a real opportunity for C-Map.

Sync on PCs

Now here's an aspect of Navionics Plotter Sync that surprised me bigtime and very pleasantly: If you've enabled Sync My Data in the Boating app and you log into your Navionics account on the Web Chart Viewer, you can create, edit, and manage routes just like you can with the app. Except, of course, that means you can be doing it with a PC's bigger screen and a faster processor, not to mention mouse and keyboard, and those remain the best tools for thorough route building in my experience.

The bigger picture is how the Chart Viewer confirms that your Route Archive is truly synced to the cloud and not just stored on your phone or tablet and maybe Plotter Synced to your boat system. And that led me to spend more time editing the archive and creating routes just to have on hand. And note that I'm not stuck in Navionics world if something better comes along.

In fact, one reason I was looking for a good routing tool (to use in earnest, not just test) was the retirement of the old PC that once made Coastal Explorer's excellent routing available at the lower helm. It does not have autorouting, but I do miss CE features like WPx, I admire other PC charting programs like TimeZero, and I may change primary tools again. But did you notice that Plotter Sync files are in the standard .gpx format? That means I could stick a Navionics SD card into Gizmo's remaining PC and import the whole "All-Routes" file into CE, no problem.

Here's an even geekier way to see what I'm talking about, and also that the .gpx flexibility applies to marks as well. I guess you can say that Navionics' remarkable Dock-to-dock autorouting can be used in just about any charting app, with a little work. And they can live in your own cloud storage even if you end the subscription that makes Dock-to-dock and Plotter Sync exporting possible.

Sync on Android

I also tried Dock-to-dock routing and Plotter Sync on the Android version of Navionics Boating running on my Samsung 4 and it worked fine. And while I don't find even a high resolution 4-inch screen sufficient to properly check a route, again this app instantly synced to the Navionics cloud (as long as the phone had service) and that meant the routes could be vetted on a much bigger screen.

Note how I have highlighted the caution Navionics often expresses, and please take it seriously. Good routing is a valuable tool, but hopefully only one in your navigation kit. I fear that even the most experienced of us are getting a little lulled, and I'm working on an entry that illustrates, as well as the Garmin app gift story that's coming very soon, plus a look at how the stalwart iNavX nav app has evolved.

Finally, check out this final screenshot. You may have noticed that Navionics Dock-to-dock often creates a lot of waypoints, and they can look pretty messy when zoomed out. But the abundance of turning points also means that a Plotter Sync route can use your autopilot to precisely steering a tight, winding channel. I've rarely allowed Gizmo's autopilot to steer a route, but I'm experimenting with it now, cautiously.
