The brand new Simrad Go7 looks like an all-glass version of the Simrad NSS7 evo2 Combo, but its design may actually define an interesting new “standalone” glass bridge MFD style that trades some of...
There are several reasons that a yacht or workboat might want to use an AIS Class A transceiver instead of Class B, even if they’re not required to. With Class A you’ll be seen by other boats from a greater distance because you’ll be transmitting at 12W instead of 2, and you’ll be tracked much more smoothly — particularly if you’re going fast and/or manuevering — because the Class A update rate for dynamic data like position, speed, and heading is much more frequent than Class B. The problem is that the total install cost of Class A can be quite high and especially annoying on a modern boat with a NMEA 2000 network — despite what you may have read on Panbo! — because no Class A truly supported N2K until the AMEC Camino 701 came along (and it’s not perfect yet)…
Two Maine blizzards later it’s nice to recall that just a week ago I was casting a lure off a similarly tricked-out Yellowfin 24 Bay Boat. I didn’t land a pose-worthy fish like my friend Chris Woodward, but the important thing about this photo is how well that trolling motor is holding an “anchor” position. Note the nonchalant skipper, despite a brisk wind and strong current both pushing him toward the channel marker aft, not to mention rocks to starboard and us to port. The pro I was with — the impressive Tom Rowland of the Saltwater Experience TV series — seemed equally confident about the reliability of the MotorGuide Xi5 and its do-anything integration with the twin Lowrance HDS 12 Gen3 displays, and it was easy to buy his claim that the combination has significantly improved his boating life.
This morning Garmin announced the $900 7-inch GNX 120 and the $1,500 10-inch GNX 130 (above) with planned delivery in February and May respectively. They use what’s called “high-precision glass-bonded monochrome ultra-glow LCD displays” and the data backlighting can be switched to most any color. Set up is done with those onscreen touch buttons or with a new GNX Keypad . Over 50 NMEA 2000 data types will be recognized and there will be five display configurations including “single, dual and triple functions, plus Gauge and Graph mode”…
It’s not on the Fusion website yet, but the MS-BB300 black box marine stereo was introduced in Fort Lauderdale — press release here — and is scheduled to ship this month. In a way it’s Fusion’s first black box unit, but then again they built the trailblazing Simrad SonicHub in 2010 and then the Garmin Meteor 300 last year. In fact, the BB300 is very similar to the Meteor 300 and whereas Garmin acquired Fusion in May, the BB300 can be viewed as a statement about Fusion’s continuing independence. The Meteor may integrate with non-Garmin displays over NMEA 2000, but the BB300 promises N2K Fusion-Link integration with many current MFDs from Humminbird, Murphy, B&G, Lowrance, Simrad and Garmin. A further indication that Fusion is going to keep on innovating in concert with multiple partners was a preview look at four new marine stereo heads that will be formally introduced early next year…
Gizmo is fenders down, awning up, in bustling Baltimore Harbor, and I have tales to tell. This old powerboat sails! That’s no surprise given her windage, but now I have precise data about how much wind (and current) can help her along thanks to a fuel management system. In this photo, for instance, we were making around 10 knots over the ground at 1,350 RPM but still getting over three miles to a gallon thanks to a stiff easterly wind pushing us down Long Island Sound. That’s a wake-pulling, inefficient RPM when running on flat summer water in Maine, but is much easier on crew and autopilot when in following seas like these. While I’m usually willing to spend more fuel money to shoulder through conditions like this, I was pleased to learn that the dollar difference wasn’t great…
The press release (PDF here) for Furuno’s new color 711C autopilot control describe it as “completely redesigned to provide an excellent match with Furuno’s flagship line of NavNet TZtouch MFD’s… right down to the control knob!” There’s no denying the similar handsome styling, and doesn’t it make you wonder if Furuno will eventually offer a color NMEA 2000 instrument display with the same standard DIN size and 4.1-inch color screen? That’s 100% speculation on my part, but doesn’t it make sense as Furuno finds itself competing with Raymarine, Garmin, and Simrad over the glass style helm that the TZT Series arguably spearheaded? The MCU002 remote TZT keypad, also now official and shipping, seems like another step in keeping TZT competitive.
It’s taken a while but I am becoming quite fond of the Simrad RS35 VHF radio and HS35 wireless handset accessory. Panbo first covered the RS35’s nice combination of full Class D VHF DSC capabilities, NMEA 2000 interface and built-in AIS receiver in late 2012. But when I received a test unit last summer, it was quickly apparent that the radio had trouble interfacing with many N2K GPS sources (as you can read about in the comments to that 2012 entry). I was slow to return the radio for the software fix but now it’s installed at Gizmo’s lower helm and has no problem with the three GPS sources shown above and a lot more I threw at it. I’ve also seen it output AIS info over NMEA 2000 to every MFD currently on Gizmo (though there is a glitch if you also have a transponder, explained below). And while some intertesting radios have come to market in the last year, the RS35 at about $300 to $350 seems the VHF/AIS/N2K value leader (except for its sibling Lowrance Link-8 if you don’t care about the wireless handset option)…
Redoing almost all of Gizmo’s electronics has taken longer than I would have guessed last fall, when it seemed like a good idea to rip everything off the boat. And sadly I’m not done yet. But the hoped-for glass bridge theme is revealing itself and I like it a lot. But then again new equipment and even just re-installed old gear also means fresh opportunities for things not to work together correctly. In this entry I’ll go over much of Gizmo’s test setup for the next year and a half — though by design there’s room for more — and also note a couple of features that have worked well and not so well during recent shakedown cruises…
I’m not sure whether to thank or curse the Panbo reader who got me hunting for NMEA 2000 cabling equipment on eBay. There is a thrill to picking up a $290 Turck JBSS 57-811 DeviceNet multi-port junction box for about $35 to $45 with shipping (and there seem to plenty left here, here, and here). It’s beautifully made — fully potted with nickle-plated brass connectors and gold-plated brass contacts, plus a built-in voltage indicator — and it can definitely be a useful part of most any boat’s NMEA 2000 network, as I’ll demonstrate. But you may find yourself up late looking for related heavy duty N2K network components, probably getting confused by complex nomenclature and maybe even buying stuff you can’t use. Then again, you’re apt to learn how many ways there are to build a valid N2K network…
