Free Online AIS Tracking Site?

Anyone know of a free online AIS tracking website?

So, if you have an AIS then the family can look you up and you don't need a SPOT. Assuming it is on of course.

If you are in coastal waters, and in one of the areas covered.

That really is an interesting site! A sense of big borther watching is a bit hard to avoid, however, unless one is trying to hide out, that is maybe not too bad at all. A kind of a safety factor.

We are sailing a lot in the Baltic Sea with some areas with very heavy commercial trafic. Even with currently no AIS on board, I will now be able to see what is going on around me - as long as my mobile internet has coverage. This service sure is no alternative to radar, however, it provides a lot of additional information and from a longer distance.

Here's my list (some already mentioned):

boatingsf.com -- Recent Ship Positions on San Francisco Bay
shipais.com -- ShipAIS
aisholland.com -- Live AIS
ais3.siitech.com -- Login
vesseltrax.com -- Ship positions vessel tracking, vessel movement, VesselTrax,
hd-sf.com -- Hi-Def San Francisco
marinetraffic.com -- Live Ships Map - AIS - Vessel Traffic and Positions

I've embedded a MarineTraffic.com chart, primed to find VALIS if the transponder is active, on the VALIS website:VALIS

I also have an AIS receiver running full-time from my house, and I share that data with several of these (and other) networks. One of them is AisHub.net: AIS data sharing and vessel tracking

Rather than tracking AIS traffic by cellular internet connection, get a real AIS receiver. The websites are not in real time. AIS is not in exact real time either, but its much closer, by two or three seconds at most in my experience.

Just for curiosity's sake, I have watched boats in real time from my boat while passing by them while linked by cellular modem to the internet on one of these AIS websites. (yes, I do have boring days occasionally where doing geek stuff like this keeps me entertained ) The websites have too much of a time delay to rely on them for AIS navigation information.

Besides, by the time you pay for all the data downloaded to your computer through your cellular connection, you could have bought a real AIS receiver for less. I don't know what cellular modem rates are in the Baltic but in the States its around 30 bucks a month, times 12 months is more than a cheap AIS receiver. I just don't want others getting the same unsafe idea.

Confirmed - the online AIS tracking just good for the armchair sailor. The real thing is a receiver or better yet a transceiver onboard.

Not 100% right. The AIS alone will give the close warnings of up to 20 mins but using the internet will show traffic hours (days) away way outside of the VHF range limit of AIS. Look at the internet as "traffic advisory service"

That was my idea, too. Sorry, if my term "around me" gave an idea of things within a too short range. I sure agree that using these services for real time navigation would definitely be very unsafe.

My idea was to be able see what is going to happen over a longer period of time. By that I mean within the next hour or so, not within the next few minutes or seconds. There are some areas at Baltic Sea (and that is unlikely to be the only place) that, from time to time, seem to have a bit too much commercial traffic on wide deep water zones and VTS-areas for it to be comfortable for a leisure craft to go through. There also seem to be periods of time with virtually no commercial traffic at all. That is hard to anticipate with radar, even less so by visual observations. The AIS data provided by these services is helpfull on getting a roufh idea how it is going to be within the next hour or two. A delay of seconds or even several minutes is not interesting for that analysis.

Re: Free Online AIS Tracking Site?

Also try AIS vessel tracker VesselFinder . It is quite young but promising
