Stuck in an office far from your boat? Or maybe your mega ride is in the yard for repairs? Well, then, scooch on over to Intelisea, a relative new comer to the world of high end monitoring and control, and enjoy some mouse time touring its online demo. The software design is elegant (and admired in the programming community), and it’s fun to think of yourself minding a 100+’ yacht packed with sensors and PCs. Intelisea systems are being installed on three large new yachts right now, but the builder is so far unwilling to publicize them (frustrating for the sales guys!). The systems are “complete sensor-to-user solutions” and, of course, very customizable, but Intelisea does quote a “standard” price of 60k for a 30m yacht.
The perfect complement to your ultimate helm full of screens and buttons? How about a plush leather Stidd chair…maybe even, as here, with joystick and trackball controls built right into the arm rests? Stidd virtually owns the high end helm seat market, but I’m sorry to report that something seems to be amiss. In fact, it’s not really the sort of story I like to cover, but when three independent and reliable sources voice similar concerns to me, all unsolicited, in just over three months, I feel obliged to speak up.
First, an otherwise cheery megayacht captain showing off a major rebuild grumbled about how much trouble he’d had getting something like a $100,000 worth of Stidds, citing very poor communications and multiple failed delivery dates. Then a friend having a custom boat built called me out of the blue to ask if I knew anything about Stidd; he has a friend who raves about Stidd’s customer service, but this fellow’s boat builder couldn’t get straight answers about product availability, if his calls were returned at all.
When the owner himself stepped in, he claims he couldn’t get Stidd to take his check, let alone give him straight dope on product availability. He—quite experienced at business—is the one who suggested that Stidd, and its prospective customers, might be suffering through a “success disaster”. And he has purchased his chairs elsewhere. Finally an industry insider I mentioned these reports to allowed that his company has also had a tough time with Stidd…poor communications, unpaid bills, etc. Three strikes and you’re out? I don’t know about that, but it sure sounds like getting a fine Stidd chair has become a hassle.
“Honey, I think that man down there kneeling on the water taxi float is drowning a cell phone or camera or something!” I must have looked weird trying to see if this borrowed Olympus Stylus 720 SW really could survive a salt water dip. I took pictures underwater (of murky Boston Harbor), rinsed the thing off under the tap, above, and… it’s still working fine. That’s impressive, and very nice to have around a boat (tip of the hat to Eli Boat, where I learned about it). But I’ll leave the extensive reviews/feature lists to the pros at Steve’s Digicams, Digicam Review, and Digital Camera Info—so I can just bitch about some minor issues:
* Why would Olympus use what seems to be a proprietary mini USB plug? That’s it at right (photographed with the 720 SW) next to a normal mini USB plug which works for my Canon XT camera and all sorts of other devices. And why couldn’t its relatively small battery be charged via the USB cable (like my new Motorola phone)? At any rate, owners of the 720 SW do have to drag along a special interface cable and a charger that’s bigger than the camera.
* While the 720 SW has lots of shooting modes—some very specific and useful, like shooting through glass (changes how the autofocus thinks)—it does not let you use traditional camera settings like shutter speed and F stop, which traditional photographers (like me) may find quite annoying. It also has no view finder at all and, though the LCD is brighter than other digital cams I’ve used, its still hard to use in bright sunshine.
* Finally, like the folks at Digital Camera Info above, I wasn’t all that tickled by the quality of the photos the Stylus took. Below, and bigger here
, is one of the best (a 2 photo collage, actually, showing the view from my roof). But then again, I am used to a very good digital SLR; I suspect a lot of people will be pleased with this camera’s performance, and especially its ability to take abuse.
I wear a watch with hands, but I’m not crazy about traditional engine gauges, especially when there are rows and rows of them, and most especially when they’re digitally rendered. Yes, a screen like this SmartCraft/Northstar combo looks ‘wow’, but isn’t Simrad’s version above, bigger here, much more screen efficient and informative? By my count, the bar gauges on this half display represent nine data points, or eighteen dials with dual engines. I haven’t seen this monitoring in actual use, but I’d hope that there could be ticks for ‘normal’ values, and maybe changing or flashing colors for critical values. Electronic engines combined with the smarts and displays of navigation electronics offer such wonderful possibilities (which, of course, is why the break up of Brunswick New Technologies seems especially mysterious).
Note that Simrad can display data from engines that use the NMEA 2000 protocol, or can speak it through an electronic bridge. Note too that this screen also shows Simrad’s unique radar overlay “sandwich”. See how the yellow targetry lays over the charted land but then the nav aids lay over everything (like the lighthouse at about 2 o’clock and 2 range rings from the boat). This is a little nuance that everyone else should copy!
Volvo also introduced an omni-directional no-thruster-needed joystick at the Miami Boat Show. It has a computerised control module running a pair of independently turning IPS drives, like Zeus, but doesn’t have Zeus’s nervous system. That’s me trying it above, and while it just can’t have the precision of Zeus without the feedback, it too is a big advance in easy boat handling (plus it’s available right now). So, looking forward, we see two major marine engine manufacturers with new drive systems that offer significantly easier handling (and some other features) and are very electronic.
If I was an independent electronics manufacturer I’d be nervous. The Brunswick team—Mercury, Cummins, Northstar, and Navman—are already a little ahead in terms of the relatively simple business of putting engine data onto a CANbus (SmartCraft) so it’s available at all displays. I know companies like Lowrance and Raymarine are trying to get this sort of engine relationship using NMEA 2000, and there’s been progress, but once systems get as complicated as Zeus I doubt that multiple manufacturers will be involved. In fact, a Zeus engineer pretty much told me that it would be impossible to develop something like station holding unless it was all in-house (and note, you Ethernet freaks, that it’s all done with CANbus). Thus I found it interesting that Altor, the Swedish equity fund that’s taken over both Simrad and Lowrance, also just purchased a large Swedish boatbuilder with close ties to Volvo Penta. “Is this the beginning of a Nordic-centered Brunswick,” is the question I asked in my latest PMY column (mostly about Lowrance, and hopefully online soon). Will other engine and electronics companies merge or make alliances? Will all this push the independent players to greater support of NMEA 2000? Time will tell.
So what do I mean that the new Zeus propulsion system has nerves as well as brains? Well, hooked into the drive controller is an ultra high precision GPS and inertial navigation sensor which feeds it fast updates on the boat’s location along with which way she’s heading, sliding, twisting, rolling etc. Thus the drive gets instant feedback about how well it’s doing what you asked it to do. In other words, if you’re coming alongside a dock and you push the joystick a little bit to starboard, Zeus will take you a little bit to starboard no matter if the current or wind are pushing you hard toward the dock, away from it, or in some other direction. Zeus can do what the very best boat driver does, i.e. observe what the yacht is actually doing in real time, figure out all the forces involved, and compensate for them to get her to go where he wants her to go. Of course the ultimate expression of a totally integrated drive/navigation system like this is its ability to hold station, which seemed rock solid during the demo. It works so well, in fact, that the Cummins guys say they have put Ingenuity next to dock and stepped ashore—no dock lines (though that will never be an advertised feature). That well!
Now it must be noted that the specific navigation sensor hardware being used on the demo is apparently a very expensive Oxford Technologies RT3000 working with private Omnistar differential GPS corrections, which adds a serious subscription expense. But it’s clear that Brunswick’s electronics division is hard at work trying to provide the needed level of precision by the time Zeus becomes a real shipping system. In fact, Zeus may explain why Brunswick picked up MX Marine, which I couldn’t figure out last Spring. The image above shows a Navman/Northstar auto pilot that’s been souped up to work with Zeus’s amazing capabilities (note how the pilot is neatly showing you what the drives are up to as you cast a line, or take a picture, or whatever). It seems obvious that many Zeus boats will be Brunswick hulls with Brunswick drives and Brunswick electronics—all one—which is worth one more Zeus entry, tomorrow.
Above is the Zeus demo boat, which has just departed a slip at Miami’s Sealine Marina and now—instead of the normal hard right, hard left exit—is going dead sideways down the channel. Leaving those bow lines neatly on the pilings was also impressively easy—no stretching—because the driver could bump the bow where he wanted it with just a little twist and push on the joystick. Now omni-directional joystick control, typically using twin engines and a bow thruster, has been around for a while, but Zeus is more powerful and much more precise, and eliminating the thruster eliminates the weakest link. Whereas close-quarters maneuvering is about the hardest thing to learn about boating these days, this is a revolutionary development. So how the hell does it work?
Well, surprise, there is a micro processor involved! Zeus’s control module can steer, shift, and throttle each drive independently…drives which can turn 45 degrees outward and 15 inward, and can do so at a screaming 45 degrees per second. Hence the driver’s simple command to go sideways, or any which ways, results in some complex vector analysis and propulsion commands that only a human trained like a helicopter pilot could pull off (illustrated below). So Zeus is way beyond drive-by-wire technology; it has brains. In fact, it has a nervous system too, which I’ll explain tomorrow.
Above is a 42’ Maxum that Brunswick, specifically the Cummins MerCruiser division, was using as a special demo boat at the Miami Boat Show. Obviously (bigger here ) it’s loaded with Northstar’s new 8000i multifunction displays (and, yes, that lower one seemed a bit odd as you could kick it if you were being ‘casual’ like this model). Now I’d love to test the 8000i on the water (especially once the finished system ships in June), but this demo was much more about that fat joystick, and the engines, drives, and electronics it’s attached to, all called Project Zeus. I got to experience it myself and, by golly, it’s a very big deal indeed. The drives are similar to the IPS system that Volvo introduced last year, except that the props face aft (which I, from the bays of rocks and lobster traps, strongly favor). I won’t go into Zeus’s claims of efficiency, low noise, etc., though you might want to check out the press release. What I want to tell you about is how I watched a guy joystick this boat’s bow within a few feet of a day marker and then do a 360 around the mark with the bow always within those few feet. I also saw how you could push the “hold station” button on the Navman pilot and boat would sit exactly in place despite wind and current, and without thrusters. This is really revolutionary stuff, and important, I think, to the future of boating and marine electronics. More tomorrow.
I’ve been posting on Panbo for almost exactly a year now, and one of my first entries was about the sailing version of Airmar’s WeatherStation. While I’m sorry to report that that product still does not exist, the powerboat version does and I’ve been testing one. Above, and bigger here, is a screenshot of the PC software that comes with the ultrasonic (no moving parts!) sensor. This particular screen shows the controls available (left) and also what data can be graphed over time. Clicking on any of those graphs switches it to the gauge-style real-time reading. The software is very easy to use but needs some work; for instance, the wind speeds are graphed to a 0–100 knot scale, which means that low speeds hardly show any differentiation. And wind direction history is not kept, which is something that must be fixed for the coming sailboat version (which won’t have a GPS, but will have an inclinometer supposedly able to correct the wind sensor for heel).
But I quibble. There are a lot of neat ways to use the WeatherStation, well illustrated in its latest PDF brochure. I have most of the setup below working (I just haven’t installed the “Smart” depth/speed/temp sensor yet), and it’s a powerful little network. A PC charting program like CE easily collects wind/GPS/heading/air temp coming out of the optional combiner via USB at 57,600 baud, plus the Furuno RD30 (a very handy device) provides alternate data display, and there’s room to run more NMEA 0183 devices into or out of the combiner. Nice detail: according to the WeatherStation manual (another PDF) the combiner favors alternate GPS or heading inputs over what’s built into the unit. I think that means that the built-in sensors can serve as automatic back ups. Nice!
I mentioned OctoPlex when it received a special mention at METS; now I’m trying to write a column about it and the whole coming revolution in marine power systems. It’s not coming easily, I’m way past deadline, and so this will be short! Here’s the deal: electronic circuit breakers combined with data networks like NMEA 2000 mean the end of conventional circuit breaker panels. The concept is often called “distributed power” but Nigel Calder also uses “the three cable boat” in a series of articles he’s done recently in Professional Boatbuilder, Sail, and Yachting Monthly (none, unfortunately, online, but look down this page for Nigel’s pithy answer to the question “should I try this now”)). In its simplest form plus and minus cables carry power around the boat, teeing off wherever needed to an electronic circuit breaker (ECB) which is controlled by the third (data) cable. ECBs are also known as MOSFETs and they’re complicated animals, but have features like the ability to constantly measure voltage and amperage and even modulate amperage (i.e. dim light circuits). Combine those features with networked, microprocessor-based switching—and, hey, you might as well throw in tank, bilge, etc. monitoring since you’ve already got the network and screens—and you start getting something as powerful as OctoPlex. Check out a much larger version of the schematic here. This system can automatically shed power loads, protect individual circuits against brown out, setup custom dimming programs, tell you if a nav light blows out, and so forth…sky’s the limit. But can things go badly wrong on the three cable boat? Hell, yes! Which is why OctoPlex is redundant every which way. More on that later.
