OpenCPN is completely real time. It gets its AIS data directly from my boat's AIS receiver, and operates in free-standing mode without any Internet connection.

I had expressed concerns about the MarineTraffic.com website and MarineTraffic smartphone apps. Those get their data over the internet through a network of volunteer receiving stations that upload their data to a central server. The website warns against using their data for navigation. I am more concerned about blackout zones than time delays, since one of the "volunteer receivers" could go down at any time without warning, leaving certain regions with no coverage.

This is very true. I have a buddy sailed up to RI. He and I planned to rendezvous in open water and flotilla for a week up the coast. He had AIS broadcasting, so I used my iPad on marine traffic to find him. He was there one minute, gone for an hour, back again. It was rediculous. I finally called him on his cell and asked him to read me his coordinates, which I just sailed toward. When I finally found in the binoculars about 5 miles away, he still wasn't on the app.

Nice. Do you know the integration details?

In spite of my comment about daytime readability, I've been considering going this route myself. My old C80 has screen damage. I am considering taking taking that as an upgrade opportunity, but the cost of a modern MPD with a similar screen size is considerably higher than the cost of a lower end iPad plus water proof case.

But integrating into you on-board systems is more than just installing the right apps on your iPad. Others have mentioned NMEA wifi bridges--what are people's experience with those? How solid are they? The sort of fiddliness we are used to putting up with for home networks would not be not good for marine instrument networks. The last thing I want to do is troubleshoot a wifi connection during a blow or have my sounder stop reporting in skinny water.

The big marine electronic venders seem to almost willfully get wifi integration wrong, doing things like insisting on hosting their own network rather than joining an existing one. That makes it hard to do things live internet integration via a phone or iPad.

What kind of AIS receiver did you get, a stand alone or one associated with a fixed VHF like the Standard Horizon VHF.. How do you incorpoate that into your netbook? Will it blue tooth or do you have to run a direct cable.

Minnie, I have found and use a real time AIS for the I Pad/ Droids. Its not free, but I got it for free as I was one of the first 10 to install it and test it out last year. Its called Boat Beacon. I have tracked it against my Raymarine integrated AIS transciever though the chartplotter and it is dead on accurate in real time.

The new Raymarine have wifi and bluetooth capability, and an I pad app so you can use your I pad as a second monitor or remote and see everything on the CP screen. You can also upload from one to the other via USB port or wifi.

Re: Ipad as sailing instrument....

I went with a Ray E7 and used NMEA 2000 for my triducer and wheel pilot. It all integrated as advertised. Ray also has an Ipad app so you can mirror the E7 and control it using its own wifi. Just started playing with it, but it seems to work.

Re: Ipad as sailing instrument....

Joel,

Youll be real happy with that unit.

I wish they had the wireless available in the c90w last summer when they replace the lightening strike stuff. The c95w now has it also.

I need a larger screen than the 7 as my eyes are older than yours

Re: Ipad as sailing instrument....

The 9 inch screen is sweet, but there is a huge price jump from the 7 to the 9! That's why I wear bifocals! I'm hoping Defender has a deal on AIS this week so I can add that to the network.

Does it still rely on shore receivers? How do they keep it real time?

Requires a constant internet access so only for coastal cruising for the most part. It is not a replacement for real AIS nor should it be used for navigation, but it is better than Marine Traffic ap

Does your boat show up on AIS as well?
