  1. Hence the term "not enough alone, for sure".
  2. You should not even need to trust their encryption, so it does not matter as long its not trivial and knowing Tesla/SpaceX/Starlink for sure it is not. As said, security needs to be layer above the transport. Always has been like this.
  3. For this level of sensitivity, its not like you can hide your transmission on radio level that well anyway. Especially in the middle of the sea with no other emitters present. And as far as I understand, SL transport layer has normal level encryption and safety in place. Enough for casual use, but for more sensitive content not enough alone, for sure.
  4. Why not? Antenna can be (gyro) stabilized or made multifaceted AESA array for a little higher price. Now with incoming sat to sat laser links (first already up), I don't see why not.
  5. What does a (satellite) communication system have to do with encryption? Just like any comms system, encryption is built on top of the communication layer. Only way to make sure, ask Google (I mean literally them) how they know.
  6. This is indeed strange. There is plenty of SAT-AIS reception from the bay, and a lot of traffic. Actually seems most North Atlantic is almost empty of class B SAT-AIS boats, South Atlantic and another Oceans there are many present. Might be an issue or intentional. BTW situation with SAT-AIS is improving, was it yesterday that SpaceX launched again multiple satellites with SAT-AIS receivers, number is increasing all the time. This won't make it to this race, but next for sure.
  7. Also it is bit pointless to compare a non foiling and a foiling rudder. The loads involved and construction are and must be very different.
  8. I don't see cameras seeing that well when it matters. Radar evolution is the key, me thinks.
  9. This will not be easy. Ocean surface in a storm and going fast is about the hardest environment to operate, sensorwise. Sonar will not work well above cavitation speeds, IR/camera won't see almost anything, radar might, but the resolution is not there yet - though this improves fast with FSD-cars. Maybe need to think of a new approach. Just-in-time microsatellite highres SAR mapping of the path forward of the boat? Iceye is lauching three more sats just today, and the teams have the money... 24/7 coverage will require a _lot_ of birds.
  10. - Ben Lexen, circa 1982. Genius of a man.
  11. Bummer. Again. Hmm. Maybe nextgen record breaker boat will be a catamaran. Modern take on Team Philips might be interesting/efficient. Fully foiling, long/tall foils to get the ride height, two wing masts with smallish soft cloths, designed to be driven with a small crew from inside a bat cave on each hull, pod racer pod in the middle for steering. One hull for the French, another for team Monsieur Alex L'Ugoboss. Throw in an Italian cook from team Maserati and success is almost guaranteed.
  12. I would want to see some hard data like polars, on similar conditions. There are quite substantial improvements outside foils as well, in eg aerodynamics and systems. These cannot hurt performance, even in non-foiling mode.
  13. What is the actual reason causing these boats to be "significantly slower"? I can only think of extra drag caused by the foils in displacement mode. Can they be retracted, at least partially for sure? Some hard data would help.
  14. Well, it is better than what Vesselfinder shows, which is quite anemic. Would be nice to have a good WX + sat ais in one view.
