    Thank you for your post.

    From what I can see, her latest position was received for FLAT OUT was on 2023-01-11 12:43 LT (UTC +10), at EAUS - East Australia with Latitude / Longitude: -23.14993° / 150.9377°

    I would like to explain that the lack of Updated Positions of a vessel can be a result of a number of factors.
    Signal strength, functional transponder, local (vessel area) and surrounding (nearby stations) weather conditions, temperatures, traffic and the satellite constellation frequency are some of the most important ones.
    You can learn more about them here:

    Further to that, I would like to inform you that in case the vessel is sailing far from our terrestrial stations, she can only be tracked via satellite, which may be less effective if the subject vessel is equipped with a Class B AIS transponder, such as FLAT OUT.
    Such units are smaller, simpler and lower cost compared to Class A transponders but their signal is weaker making it harder for satellites to pick up AIS messages coming from them.

    Last but not least, could you please be so kind as to let me know the current position of your vessel, so as to check our coverage in that area?

    Kind regards,
