Dave aka chef2sail: Did you get a chance to do a DSC radio check this weekend? Just wondering what result you got.

Since there may be others who are tempted to forgo the expense and use their iPhone or other mobile device instead of a real AIS receiver and traffic display, here're the answers to that question:

1) The AIS data received on your iPhone, laptop, via the Internet, or by any source other than an actual AIS receiver located in your vessel is posted to the Internet by volunteers who have receivers located in fixed positions (often far from water). I'm one of those volunteers. The vessels you see near Half Moon Bay, CA on marinetraffic.com and aprs.fi probably came from me (look for "N8QH" as the source). My receiver is in my sailboat, from which I upload a continual data stream to marinetraffic.com and aprs.fi via the Internet. And when my boat leaves the dock, I disconnect from the Internet and ... POOF! ... all of the data I am supplying, and seemingly all the AIS-equipped vessels in that area, VANISH. There are no other volunteer receivers that cover the area because the surrounding mountains block reception. This is true for many other volunteer receivers: their receivers are only on part-time.
2) If you think you can use AIS data from a service via your iPhone for collision avoidance, then read the fine print. Here's an example warning posted on marinetraffic.com:
"Vessel positions may be up to one hour old or incomplete. Data is provided for informational reasons only and is not related by any means to the safety of navigation."
The author of that warning isn't exaggerating or just trying to avoid some obscure legal liability. For the SF Bay Area, there are only a handful of volunteer receiving stations, and the coverage in the Bay is highly incomplete. Large swaths of the Pacific Coast (and most of the remainder of the planet) have no coverage at all. If you don't see any vessels on your iPhone AIS app - that doesn't mean there aren't any vessels there.

So don't cheap out by trying to use your iPhone along with some external service to avoid getting crunched by a freighter! The data is unreliable! It's false security. The only AIS data you can trust is the data received by an AIS receiver located in your own boat.

Re: Boo TowBoatUS! They don't connect their own DSC

Yes I agree. I like the chartplotter which is inegrated with all my Raymarine insturments...autopilot, AIS, radar, deptfinder, and wind as well as engine instrruemtation.

I can Set my screen split with just two active components, which I usually do with radar side by side with cartigraphy and ais or superimpose. You can actually divide the cscreen into 4. I use my IPAD to move around the boat and pllot course and can lay it into the chartplotter. Everything on the plotter shows up on the IPAD. It also shows up on my droid phone, but my old eyes along with the bouncing motion of the boat make it a kittke more difficult to read.

I am not as computer savy as Rick so my high tech is going to be different and have to be set up for me. I also dont hink for the type of sailing I do,,,offshore sometimes and night...that a netbook topsides as my primary ( after charts) will work. I love the new AIS integration. HOoever it can be a bit ,uch sometimes

On our last trip to the LI Sound and NE we were heading up the Jersey coast at night. During the day we stayed 3-4 miles off the shore and could see everything visually well so no need to radar, AIS. As we approached Sandy Hook at dusk I turned on the radar and AIS and had a 5 mile ring set up and it looked like an acrade game. TMI One I split screen it was better. The fast ferrys from Atlantic Hihghlands to Manahattan looked like comets accross the screen.

Re: Boo TowBoatUS! They don't connect their own DSC

Dave, Rick,
I think we're more in agreement than we realize.

I'm envisioning a rugged, daylight viewable bluetooth tablet designed to work in concert with a dedicated chart plotter.

The chartplotter is rugged enough to be at the helm in any conditions and its interface is easy to use while piloting the boat.

A dedicated tablet allows you to plan your trip, enter way points, bring up Active Captain info, look at aerial photos of your approach, etc., all on a much larger screen that's easier to interact with. If it's rugged and daylight viewable it can be used above or below deck. If it's running Android it's expandable with apps.

The ability to recognize and sync with a bluetooth headset and phone would allow you to call ahead to a marina by clicking on it or choosing it from the chart plotter. Tie the VHF in via bluetooth and that same headset or earbud could be used to make hands free VHF calls or calls to an AIS target. Think about the advantage of having your hands free on an emergency VHF call.

Or how about being able to use two bluetooth earpieces through the system so you could talk with someone of the foredeck when anchoring or docking?

I think we're just starting to scratch the surface of this technology.

And Rick I like the idea of being able to rotate the plotter. Mine is on a swivel so I can see it when I'm forward of the wheel.

Re: Boo TowBoatUS! They don't connect their own DSC

A question out of complete ignorance, could I have the same connection with a bluetooth IPAD? and is there an app?

thanks,
Ron

I fully admit that am a special case. On this boat I am a fair weather daysailor, in fresh water. Also I'm a geek, and willing to fiddle with a complicated schematic, special configuration files and .bat files to tweak the software to do exactly what I want it to do (such as open two windows in very specific locations on the screen). This is potentially very different from other Sailnetters.

However, for those with similar skills to mine, my setup does offer some very nice advantages in the split screen, and the ability to turn the screen in different directions. And the software has been rock solid all summer long. I haven't had to reboot the computer once - I just put it to sleep when done, and wake it up next time. As my sailing technique has evolved on this boat, I find myself moving around the cockpit a lot (steering from the side with the wheel between my legs, or from the catbird seat), and could not imagine having my chartplotter on a fixed pod. But that's just on this boat in my current sailing area. I could imagine it being very different on a different boat.

I'd be surprised if we don't see daylight viewable, waterproof tablets in the not to distant future if someone isn't already making one. It just seems a logical extension for Garmin or Raymarine to do.
I doubt they would replace fixed ones . Thats why they are making them bluetooth and wireless in as small as 7" models so you can stream them into your i pad or droid.

There are some advantages to having the chartplotter fixed at the helm or nav station in a navpod.

Start with its a nice clean streamlined look and installation. Easy to run power and keep it powered. Less suseptible to damage as not only are they made for marine environement, so are their charging/ power connections.

Ahh, that makes sense.

I sat on the perch seat up under the bimini to stay dry, and kept a lookout while the computer steered the boat under motor power.)
That's very cool. Connecting my chartplotter to my autopilot is on my to-do list, but sailing on the bay it just never seemed all that important to get it done.

The 2150 sends AIS via NMEA to the RS232 end of the Bluetooth adapter, which broadcasts it to any Bluetooth enabled device that wants to listen.

Sad that they do not follow their own advice! They've got a press release out that that says they'll do this, but they don't.
