Sorry, there is no such thing... From MarineTraffic's FAQ page (emphasis mine):Hi All,
Looking for a www site that I stumbled across once that showed everything with an AIS signal on the planet. What do you use for your iPad?

It's scary how many boaters today appear to be viewing these sites as if they are an equivalent substitute for an onboard AIS receiver...Data provided can only be used by Internet users for informational reasons only and they are by no means related to safety of navigation. Information provided may be incomplete, obsolete or contain errors and cannot substitute the on-board safety equipment and of course the good seamanship.

Yup, I agree...that's why I just installed a new VHF with AIS receiver. But before I had that, I used the iphone app. I knew it was not complete, but being aware of that limitation it was better than nothing.Sorry, there is no such thing... From MarineTraffic's FAQ page (emphasis mine):

Gotta start somewhere guys... radar, plotter.... We'll get there. It's the big mother tugs and ships I worry about in the limited visibility. A little information is better than none. Thanks.Sorry, there is no such thing... From MarineTraffic's FAQ page (emphasis mine):

I suppose, but keep how it works in mind. These websites rely on local receivers that transmit data to the internet, which the site picks up, translates to its graphics and sends back to you. If you identify a large vessel, via an app, in limited visibility and adjust course. for all you know, you adjusted right toward it. Worse yet, if you are lulled to think there isn't anything ahead and go below to use the head, there is really no assurance........A little information is better than none. Thanks.
I just want to "ditto" this, because it is so important to remember. Certainly, more information is better than less. But do not fool yourself into thinking that any of these websites will show you "everything with an AIS signal on the planet." They won't. Not even close.I suppose, but keep how it works in mind.
Its not real time. It's normally delayed through a number of reasons: Browser refreshing; longer time to get through the reciever station system and to the internet up and down., but as far as I know, it's not real time? Am I correct in that assumption?
so its good for putzing around but got good for navigation, safety etcReceived:

I think I have to agree with Minnewaska here. The data will be delayed, so where it is on the screen is surely not going to be where it is on the water.I suppose, but keep how it works in mind. These websites rely on local receivers that transmit data to the internet, which the site picks up, translates to its graphics and sends back to you.

We don't transmit AIS at all for that matter, so you'll never know whether we're out there. A buddy does transmit and I look to rendezvous with him frequently. I pull up the site ashore and rarely find him, even though I was just texting with him and know exactly where he is.
