In the lead-up to any major boat show there are a lot of press releases flying around. The 2018 Miami International Boat Show was no different, and one such announcement was from a new division of Brunswick called Nautic-On. While I made a mental note to see what they were all about, frankly my expectations were meager. But what I encountered was a style of boat monitoring that far exceeded my expectations.

Within minutes of announcing Garmin's acquisuition of ActiveCaptain in May 2017 commenters here and elsewhere immediately began to worry about its future. On Wednesday evening, the Polar Navy announcement above poured fuel on that fire, suggesting that the many non-Garmin charting apps and MFDs which display ActiveCaptain cruising information would lose access to the database this May. But that quote is not the whole story by a long shot. Actually, Garmin is emphatic that AC data will remain freely available to developers and users...

MIBS 2018 saw the manufacturers putting the multi in MFD, with Garmin and Raymarine each introducing multiple new multifunction app and app-like display integrations interfacing to all sorts of third party boat systems, plus consumer electronics gadgets and online services -- actually every single brand seen below, with lots more likely coming. The results are exciting, but what the heck are MFD apps? Fortunately, Raymarine is illustrating all three ways they can be created and why it's useful to know how it's done...

That new 24-inch Simrad NSO evo3 screen must look spectacular with its 1920 x 1080 pixel resolution, 1200 nits of brightness, and IPS-style wide viewing angles. And these big screens -- there will be 16- and 19-inch models too -- can purportedly be viewed with polarized sunglasses, thanks to the use of combined LCD and polarizer. The new NSO design is also packed with connectivity, including a Simrad-first J1939 engine input, and a black box processor is no longer needed. We've got details on the series, and then let's ponder recent Navico acquisitions...

As I sat down to write this article I flashed back to an eye-opening technology experience at the 2015 Fort Lauderdale International Boat Show. My wife and I found ourselves on the Seakeeper roll stabilization demo boat in the mouth of the Port Everglades inlet with a Viking 60-foot sportfish doing circles around us throwing as big a wake as possible. Our demo ride led to a major install on our Carver motor yacht, which I can recall in vivid detail, but which also significantly improved our subsequent family voyage around the Great Loop...

It seems appropiate to kick off 2018 with a discussion of heating technology, specifically the diesel-fired hydronic system I installed on Gizmo last year. It was a significant purchase and a major install, but the 66 degree pilothouse temperature seen above certainly made my early December ICW trip a lot more pleasant. I'll explain why I chose hydronic, detail how the system went together, and profusely praise Sure Marine Service, a marine heating equipment distributor par excellence...

Simrad has now officially joined Furuno and Garmin with a solid-state radar feature using the Doppler effect to instantly highlight targets moving relative to your vessel. "VelocityTrack" can be added to any existing open array Halo radar with the purchase of an unlock code, and it appears to be the most sophisticated version of the feature yet. Simrad also created a thorough VelocityTrack presentation that even explains technical subtleties common to all such Doppler radar features. Meanwhile, Furuno is now challenging the Simrad and Garmin solid-state Doppler open arrays with its new DRS6A-NXT...

Despite incredible advances in chart availability and chart plotting, keels keep banging on reasonably well charted ledges and reefs all over the planet. Why? I've made far too many navigation errors to play the righteous scold, but I am taken aback by the tendency of boaters to blame technology and especially the recent trend toward castigating chart manufacturers like Navionics as if perfect data is a possibility or even an entitlement...

I like to write about marine electronics that facilitate safer, more enjoyable boating, especially new developments that seem headed in that direction. It's been gratifying, for instance, to see the infant Class B AIS that Panbo began covering in 2005 grow into a highly appreciated tool for cruisers, racers and fishermen. AIS is a huge success on many levels, but today the subject is two issues that may concern some Class B AIS users...
