I think your right. We rarely sleep between anchor watches in even a small storm. 12 hours ago, TIGHTCHOKE said: Data from the ship’s Automatic Identification System or AIS reportedly shows that there was a 16-minute period between the storm hitting the 184ft-long Bayesian at 3.50am on Monday and the vessel sinking at 4.06am. That's quite an AIS system they have if it can do that. Quote Link to comment Share on other sites More sharing options...

One report I read said that there was a 16 minute period between the emergency satellite beacon signal they carry going off and some other signal that relies on the power being on. The explanation was that the first signal ceased when the water flooded the electrics (apparently one of the first things to fail in marine 'problems' as salt water is a good conductor), but a further 16 minutes before the emergency beacon ceased - assumed to be being submerged (which prevents it's transmissions).

TIGHTCHOKE Posted August 26 Report Share Posted August 26 The 16 minutes is recorded from the satellite based tracking system on both yachts. The Skipper of the Sir Robert Baden Powell, Karsten Bonner, held his ship steady in the poor weather with his engine as his anchor was slipping. His crew were alert to the worsening weather conditions. It would appear that the captain and crew of Bayesian were not. Reports of the mast snapping are conflicting, we will have to wait and see, but if it is still attached it will most probably have to be cut off during the salvage operation. An awful loss of life in what appears to be negligence at best and manslaughter at worst. Quote Link to comment Share on other sites More sharing options...

We have two signal systems I think the same. There is AIS a tracker system ours is based on the VHF transmitter but there is also an S AIS that also has satellite tracking. This shows where the vessel is course and heading and produces a track. This would be deactivated if the batteries were flooded. There is also an EPIRB that is satellite based that is launched when a boat sinks or a life raft is deployed. This transmits a location signal. That could account for the time difference. We also have AIS in our life jackets which is activated on immersion. Apparently the yacht has large saloon doors (main entrance to the interior) on tracks the retaining mechanism for which is known to be problematic. When the boat heels the mechanism is incapable of holding the weight of the doors without additional strapping and they fall open. Quote Link to comment Share on other sites More sharing options...
old man Posted August 26 Report Share Posted August 26 Again, where was the anchor watch? Quote Link to comment Share on other sites More sharing options...

Interesting that the operating manual for the boat allows for the keel to be up at anchor. That the angle of vanishing stability (the point at which the boat cannot recover is only 77deg with keel up and only 88deg keel down (this is very low ours is 127 deg). That the down flooding heel angle is only 40 to 45 deg with all of the HVAC operating and air inlets open, which it would be at anchor. Also that the additional 30 tons of ballast added to the hull to increase stability for the oversized mast puts the boat 100mm lower in the water than designed making use of the lazarette problematic. The Captain pleads 'no contest' and refuses to speak further. Quote Link to comment Share on other sites More sharing options...

I still feel the Captain and his crew will take the rap. Quote Link to comment Share on other sites More sharing options...

This is what I was alluding to previously, as in "things moving forward"👍 I feel there will be two adjoined investigations,,,,, one has started, and as you say, the other one is pending.

oowee Posted September 22 Report Share Posted September 22 Now the designer / manufacturer of the boat looks to sue owners for sinking it and damaging reputation 🤣 Quote Link to comment Share on other sites More sharing options...
JohnfromUK Posted October 3 Report Share Posted October 3 For those interested, there is a documentary on ITV tonight at 21:00 (and no doubt on 'catch-up' afterwards). Quote Link to comment Share on other sites More sharing options...
