Thank you all for your constructive comments and feedback. Happy to help clarify some things from the interview which I might not be clear on.
I spoke to the captain of the USCG lifeboat after SEA WISDOM was docked at Pier 45, I asked him why he couldn't see me on AIS, he said there could be issues with his AIS system. My Garmin system was relayed to my iPad, so I video recorded the whole rescue. In review of the video, my AIS was also NOT able to detect the USCG lifeboat, however, I was able to see other boats on AIS. Perhaps there was indeed an issue with the CG AIS system at the time. This is another reason why I strive for redundancy on SEA WISDOM, just in case somebody cannot find me on AIS for whatever reason. The USCG lifeboat was doing its best to locate me visually, and there was a fishing boat who spotted me at the time, and tried to relay my position to the USCG lifeboat. USCG command center also had the race tracking URL. At the time, I increased the frequency of my tracking message to every 5 minutes. The GPS coordinates was also communicated to the USCG. Yes, somehow through all these information, the lifeboat had a difficult time locating me visually. Redundancy on safety equipment helped increase the chance of USCG locating me. And it was my responsibility to be located. I am very grateful for USCG to get to me under all these conditions.
My Iridium Go was the only satellite voice communication, I did not have a spare satellite phone. I have both InReach and Iridium Go for satellite data and SOS. I thought that redundancy was sufficient in terms of satellite communication. I was right about the data, however I was wrong about the voice . The Iridium Go voice communication was not reliable, it was at best for casual communication with friends and family. For emergency, the Iridium Go failed to provide a clear voice channel to communicate. I had full bars for satellite signal as the Iridium Go uses an external antenna. The Iridium Go data transmission was excellent and reliable. My satellite voice communications with USCG were dropped a few times. USCG even requested me to text them instead. Iridium Go texting was almost instantaneous, just like a cell phone. I would not use InReach for texting, the latency with InReach would be too slow, but InReach is a good backup. In the future, I will have a dedicated satellite phone for just voice communication. I had that an Inmarsat C 20 years ago on my last boat, it was very reliable, the voice quality was crystal clear.
I do have to think about what is my second backup steering system besides the Hyrdovane. The Hydrovane is an elegant, simple and effective steering system. I have also used Monitor Windvane extensively on a BCC (Bristol Channel Cutter), I absolutely love the Monitor Windvane. For the dislocated Hydrovane, if I was further offshore, I could have continued on slowly under sail. In fact, I sailed for 3 hours and made decent progress with the dislocated Hydrovane. It was the combination of continuous fiberglass getting crushed in the rudder box (even after I tried to stabilize the movement of the dislodged rudder), the potential of heavy current against me, the minimum steerage under engine power and the minimum maneuverability in the shipping lane, that I finally requested assistance from the USCG. I was lucky that the dislodged rudder did not cause more damage to the hull.
Hopefully I provided more color here on those topics. Feel free to let me know if you have more questions. Always happy to help fellow sailors.
