    Tried to edit original entry but forum would not produce a Submit button: 

    Correct characteristic for Point Lynas light (Anglesey 53°41N 4°29W) is Oc. 10s. NOT Fl.8s. I can confirm visual sighting as recently as this morning!

    Hi Iliana,

    Unfortunately, the AIS map is still showing the incorrect characteristic of Fl.8s. Perhaps this will change later as the update is promulgated.

    Could I also note that the Skerries Lt Ho is being shown as a vessel - travelling at 0 knots(: Might it be an idea to convert it to a light house, like Lynas?

    Dear Ralph,

    Thank you for your response.

    It usually takes about a couple of days for the changes to update throughout the website.
    As for Skerries Lt Ho, I'm afraid I was not able to locate the record.
    Could you please provide me with the MMSI or the record URL?

    Thank you in advance.
    Awaiting your future response.

    Kind regards,

    Hi Iliana,

    I've taken a screenshot of the Skerries and its location. Hope that will help you to find it. It is being reported with the icon for a vessel and is showing a speed (of 0 knots of course!). It has no range or height data. It's URL appears to be https://www.marinetraffic.com/en/ais/details/ships/shipid:849894/mmsi:992351121/imo:0/vessel:SKERRIES_LH/_:9992bd8b4749889923b87b397758a159 

    A minor point.

    Dear Ralph,

    Just a little information of another MarineTraffic user out Belgium

    If you open the following link : www.marinetraffic.com/en/ais/index/ships/all/_:8169672f79fece0a441274fe7eb472d9/ship_type:1/status:all

    and if you open all the MMSI-records of these "Navaids" you shall see that all the Speed/Course registrations are 0.0kn / -

    I think it is normal, if you know the MarineTraffic AIS-recording system the Navaids are a sort of, as we can see a,  “ static vessel ” or “ not moved vessel “.

    So, I think that it is normal that the Speed/Course registrations are 0.0kn / -

    Best regards of Belgium…

    Marc

    PS

    Dear Ralph,

    There was also a wrong uploaded photo under MMSI 992351121 – Skerries LH…

    I ask MarineTraffic to transfer this wrong up-loaded photo to the right place MMSI 992351120 Casquets Lighthouse ( my personal request  #76402 )

    Best regards

    Marc

    Thanks Marc,

    I've started using the App more widely (it's good, isn't it?!) and am discovering that many Navaids are displayed as vessels (with the possibility of moving!). In my simple way, I had rather expected fixed Naviads, such as lighthouses to be shown as ... fixed. I guess this is just the way the designers were thinking when they allocated descriptors and I'll have to get used to it.

    You might have seen the joke video of USS Montana playing 'chicken' with the South Rock lighthouse. If not, I've added a link to a Dropbox file. Hopefully you'll be able to get at it there.

    Dear Ralph,

     One thing more about the Navaids…,

     If you open all the MMSI-records of these Navaids you do not find in the voyage info things that you find for other “vessels”

    • Companies at destination
    • No past track
    • No route forecast
    • No itineraries history
    • No latest positions
    • No recent port calls

    Best regards !

    Marc

    Hi Marc,

    You've covered the point I had in mind. I've noticed previously that fixed naviads are sometimes shown as vessels in places on other AIS web sites and I've never understood it. That joke video, as well as being funny, illustrates an important point. I write a pilot (published by Imrays) and I go to great lengths to get the details rights. It seems wrong that such a basic concept does not appear to be grasped - but maybe there is a rationale for giving lighthouses the characteristics of ships (sic!) :) I'm also 'amused' by the thought that unmanned stations have a phone number (MMSI). Is it that the authority which issues AIS certificates is handing out the wrong sort?

    Iliana - any additional thoughts. It would be a pretty huge job, by the looks of it, to correct all the 'moving' lighthouses! Delighted to see that Lynas now has the correct characteristic.

    Dear Marc, 

    Thank you for your all comments and assistance, it is much appreciated.

    Dear Ralph,

    Thank you for your comments and observations and my apologies for the delay.

    Aids-to-navigation, i.e. Atons, have their own MMSI numbers and also have a separate NMEA message of their own, which they transmit through AIS transponders.

    In the same manner, some lighthouses may also be equipped with AIS transponders.
    All lighthouse in our website have a record as lights; however, when the aforementioned is the case, another page is created, which includes the MMSI number, as opposed to the 'light' record.
     
    Lastly, please note that, since MarineTraffic relies on the AIS system in order to collect for the necessary data for a number of services, whenever we receive transmissions from an MMSI number, a record is created.
    These records are created as vessels and what differentiates is the 'Type' of vessel.
     
    I hope this clarifies things.
    I remain at your disposal.
     
    Kind regards,

    Thanks for your patience Iliana. I understand that offshore lighthouses will also transmit an AIS message. Skerries & Rockabill (the two I'm using as examples) fall into that category. 
    EUREKA - Whilst writing to you about how that doesn't help, I have discovered that if I use extreme zoom, a second icon appears with the relevant AtoN data!! Up to now I've been taking a broad view and the lighthouses with AIS have been appearing as vessels, of type "Light, with sectors". Now I can see both sets of data. Lynas, not transmitting an AIS message, shows as an AtoN at any zoom level.

     

     

    Problem solved. 

    For idiots like me you might consider changing the focus parameters in the code for AtoN's (-:

    Best Regards.
