    UPDATED Thelonious II Noon Position Reports, 2021

    He's almost there! Terrestrial coverage of AIS is not good north of Oahu. I think he will come up on Marine Traffic's free service as he moves south. Their free service still shows him near California (last terrestrial fix).

    UPDATED Thelonious II Noon Position Reports, 2021

    I didn't get the email so the fix is about a half-hour late. It says the wind is a breezy 18 knots. Christian travelled 115 miles in (roughly) 24 hours. He has traveled 1219 miles, 1016 miles to go based on straight-line distances.

    Today's noon position: Thelonious II has traveled 132 nautical miles since yesterday's position, 1219 miles from the start, 1005 to go. There are some tropical disturbances in the Eastern Pacific that could have been a concern if he had left a week later...

    UPDATED Thelonious II Noon Position Reports, 2021

    I received a noon position email today. The app says the winds in his area are 13 knots at 46 degrees, temperature still 68. This is 88 miles from yesterday's position, but that reading was taken almost 3 hours late, it would have been about 100 miles for the full 24 hours. The average speed...

    UPDATED Thelonious II Noon Position Reports, 2021

    Just based on mileage he is 39.9% of the way there (887 of 2224 nautical miles) to Ko Olina. Calculating hours using a constant speed (174 hours so far) he would arrive in 11.0 days. That's leaving out the variations in the weather of course. What say the experienced sailors?

    UPDATED Thelonious II Noon Position Reports, 2021

    I didn't get a position email today from Marine Traffic. :confused: However, the Marine Traffic phone app lets you see satellite positions for 99 cents a day. His position is updated every 5 to 10 minutes. This is from a few minutes ago: His speed varies. I just refreshed and he was...

    UPDATED Thelonious II Noon Position Reports, 2021

    I did a little more reading about AIS. The satellite will pick up a class B AIS, but because the signal is fairly weak, it may not be picked up on every pass of the satellite. Also, Marine Traffic (free version) does not provide free tracking for these satellite fixes. Their paid service is...

    UPDATED Thelonious II Noon Position Reports, 2021

    There is such a thing as a roaming AIS station. That is a ship that has agreed to upload AIS information similar to the way the land stations do. I saw some pleasure boats in the Sea of Cortez that said the AIS station was a cruise ship (docked nearby). Unless Mr. Williams has satellite AIS...

    UPDATED Thelonious II Noon Position Reports, 2021

    If you register at Marine Traffic (no cost) and put Thelonious in your fleet, you can get a noon updates by email. I don't know how they are doing this. I thought he had class B AIS. Maybe he is uploading these somehow? Today's given position is 769 nautical miles from Marina Del Rey. Here...
