Genasun & Victron, power to spare? 26

Genasun & Victron, power to spare?

GenaSUN_onboard_Huckins_cPanbo.jpg

That’s a pair of Genasun LFP Lithium batteries that weigh a small fraction of what similar sized regular marine batteries would and offer a lot more usable power than even their 760 amp hour rating would indicate, because they can endure truly deep discharges and accept massive recharges.  Combine these with no less than four Victron MultiPlus inverter/chargers, which can automatically kick in extra AC when shore power or the generator can’t carry the load, and you’ve got power to spare.  Yes, this is a high end project, but note the gray diagonal planking seen behind the lithium batteries…

DY AIS200N2K, even better than it looks!

Digital_Yacht_AIS200_n2k.jpg

The picture tells a lot: Digital Yacht’s new AIS200N2K is the first AIS receiver I know of with NMEA 0183, NMEA 2000, and USB outputs. But get this: it can also multiplex 0183 input and gateway it to N2K, “so that traditional data such as depth,
position, speed and wind, which is available in NMEA 0183 format, can be converted
to N2K within the unit.”  All for $519!  The press release doesn’t say what’s coming out of the USB port, but I suspect it’s 0183 with a mix of AIS target data and 0183 inputs.  Maybe someone from Digital Yacht or its US and EU retail arm Cactus Marine can elaborate in comments, because I may lose my Internet connection any moment now…

Good gear: Gemini Marine, the strapless bimini & more

May_Bimini2_courtesy_Gemini_Marine.jpg

Did “strapless bimini” get your attention?  Well, it does involve some sexy hardware, and the finished strapless product, as seen on this local sloop, has a certain elegant attraction.  The trick is that those 1″ strut tubes seen under the port and starboard edges of the canvas each contains an internal hinge that lets the whole deal fold aft, but they also have a 10″ section of 1 1/8″ tube that slides and locks over the hinge, rendering them rock stiff.  (But maybe enough with the double entendres?)  I have not tried this hardware myself, yet, but have been watching the manufacturer, Gemini Marine Products, perfecting it for years…

Si-Tex SP36 autopilot, like ComNav’s but different 10

Si-Tex SP36 autopilot, like ComNav’s but different

Si-Tex_SP36.JPG

My first reaction to a press release about the new Si-Tex SP36 autopilot — sure to be posted at the Si-Tex site soon — was that its nifty-looking color control head above looks exactly like one ComNav has offered for a while.   Not that rebranding the ComNav gear, which has a good reputation (I think), is a bad thing.  But what’s actually going on here is that Si-Tex has contracted ComNav to manufacture an autopilot to its own specifications, and at least one difference looks like a smart idea to me…

Lowrance DSI , & Navionics goes MicroSD (Raymarine included)

Lowrance_Elite-5_DSI.JPG

Last week Lowrance announced the Elite-5 DSI and some related fishfinder/plotters, and while they’re unabashedly aimed at freshwater fishermen, there are at least two things about them of interest to others.  DSI stands for DownScan Imaging, which seems to mean that Lowrance has isolated the high resolution down looking portion of StructureScan into an even more inexpensive form.  That means a transducer that can ping at 455 or 800 kHz, trading detail for depth and breadth.  Aren’t lots of non-fishing boaters — like gunkholers and just plain curious monkeys like me — also interested in better resolved bottom imagery, even if it’s only to 100 feet or so?  That’s why I installed StructureScan on Gizmo even though the thru-hull transducer wasn’t ready yet, and I can’t wait to seriously experiment with it (soon!).  The new Lowrance plotters will also be the first I know of to use MicroSD chart cards…

SimNet network testing, & more NSE goodies 34

SimNet network testing, & more NSE goodies

Simrad_SimNet_parts_cPanbo.JPG

Years ago I gave Simrad grief for developing its own NMEA 2000 cable and connector system, called SimNet, instead of going with the DeviceNet standard as NMEA wanted.  When NMEA 2000 was just getting started, SimNet confused end users and installers alike, as would Raymarine’s SeaTalkNG, and Lowrance’s first version of LowranceNet, etc.  I remain leery about proprietary cabling but I’ve never heard of performance issues with SimNet, and I’ve never had any trouble integrating SimNet devices into standard N2K networks, using male versions of the adapter cable seen above.  Until this week, however, I’d never tried it the other way around, building a SimNet network and adding in other manufacturer’s N2K devices as desired.  No problems so far…

SRT mini AIS modules, & trouble from the East? 14

SRT mini AIS modules, & trouble from the East?

SRT_Class_B_n_SART_modules.JPG

I mentioned SRT’s amazingly miniaturized Class B and SART AIS modules back in May, but seeing is believing. In that aluminum EMI enclosure at left is a Cobalt Class B transponder complete with precision GPS engine and power supply (the board itself is inset)!  What we’re looking at is smart phone technology applied to a very specific marine use, and it shouldn’t be too long before these modules make AIS less expensive, more powerful, and much easier to integrate with other devices.  But I’m also hearing about a dark cloud looming as the marine world rapidly adopts AIS…

Camden NOAA chart changes, the questions

Camden_Channel_cPanbo.JPG

So I’ve done more research into the various small issues I’ve noticed regarding recent NOAA chart changes to Camden Harbor (discussed most recently here).  Let me emphasize small, and also my appreciation of NOAA as an agency with vast tasks and limited resources.  The intent of charting the Outer Harbor channel buoys maintained by the town, and updating dock details in the crowded Inner Harbor, is excellent; nearly every day I’m around the harbor I hear visiting boats getting guidance about these matters via VHF.  But the chart update issues certainly bring up questions about who’s responsible for what and NOAA’s quality control system, as well as ones regarding intentional and unintentional chart presentation details.  And they probably apply to the official charts all around the country…

That somewhat odd looking “waterborne structure” is Robinhood Marine Center’s first Island 40, designed to give renters who may only have small boat skills a wicked nice Maine cruising harbor experience, as in swinging on a mooring with seals, osprey, lobster men, and cruisers for neighbors, with good exploration possibilities in all directions, and with a pleasant “destination” marina nearby.  And it’s a hoot!  I’m sitting at the Tessie Anne’s spacious aft dinette right now, enjoying a cool sea breeze and the use of a well thought out battery/inverter/solar panel system…

Garmin 7000 and AIS 600, some install details

Garmin_AIS_600_back_cPanbo.jpg

Today I checked out some just-received Garmin gear prior to installation on Gizmo, and I noticed some nice little changes.  For instance, this AIS 600 has an automotive blade fuse instead of a glass cartridge and its relatively flimsy holder (which should all vanish from boats, I think).  And Garmin’s included NMEA 2000 cable is thicker than it used to be, indicating, I’d guess, some added EMI protection (needed to get NMEA certification, pdf on that subject here).  Garmin has also started using separate split screw collars — seen on and off in the photo — on lots of connectors besides Ethernet, which means easier to run cables (in some situations).  Note, too, the most LED indicators I’ve ever seen on a Class B transponder.  Tentatively speaking, the thing seemed to work pretty well too…
