- nradov 5y agoLarger vessels already transmit their position via AIS, which is helpful for collision avoidance. The problem is that you can't rely on it. Transmitters can fail or get switched off. The smallest vessels don't have AIS and probably never will. How would that work on a Hobie Cat that has no electronics at all?
- yardie 5y agoAIS has a 50ms window to transmit data on just 2 channels(69,70). Not much of a problem when there are only a few ships in a few miles radius. But in a congested harbor transmitters may never get that window in a timely manner. I've experienced cargo ships popping up out of nowhere in AIS (I could see them on radar) in Valleta harbor. A proper AP will have to ingest information from all sources (vision, sound, radar, AIS) to be able to work outside of the low traffic areas.
- Ekaros 5y agoSmallest vehicles likely never be automated. On other hand I hope everyone piloting them are smart enough to avoid the big ships. Most sufficiently big things are decent radar targets anyway. Or special military vehicles, which I expect to do the avoiding. As if you are the one that can't be seen, you better be careful one.
- nradov 5y agoUnder current rules of the road, there are circumstances where big ships are required to avoid the smallest vessels. That can particularly be the case if the small vessel is a sailboat or otherwise has restricted maneuverability (alpha flag), but there are a variety of factors involved. Small vessels operating close to shore often have no radar. https://www.imo.org/en/About/Conventions/Pages/COLREG.aspx https://www.imo.org/en/About/Conventions/Pages/COLREG.aspx
