A bad day on the ARC - a 45ft catamaran has been abandoned. The crew are safe aboard another boat.

That’s very worrying. Let’s hope the casualty is found soon. At least the water temperature shouldn’t be too cold.

Awful news, especially for those affected. Let’s hope for a positive outcome.

I can't find a reliable link, but here's a screenshot from an update from another boat doing the Arc. It's not good news at all.

YB tracker also shows following boats have changed course and there are three other boats in the area right now..
I have friends crossing in the ARC+. Thoughts are with them and everyone else out there...

Surprisingly, it seems Bermuda does not host an SAR aircraft, the incident was 130 miles of its coast. I realise it's a small island state but given its position I'd have thought some arrangement with HMCG and/or USCG would be in place to provide an air rescue service.

Are you sure? Might be a tad further away than that?

130nm feels like a typo. The reported MoB position is ballpark 1300nm ESE of Bermuda

OK. Did consider that but wondered why 1300 nm E of Bermuda wouldnt be described as 700 nm SW of Azores.

Agree sounds like a typo.

That sounds far more plausible! Very sad indeed and my thoughts are with the crew of Ocean Breeze and the casualties families & friends.

The article notes " the casualty was wearing an automatically inflatable lifejacket with a personal AIS beacon attached"
You would think this was the best kit for a MOB incident. More info needed.

Almost the best. A PLB in addition to the AIS might help although the PLB’s in our lifejackets require the casualty to activate them. (The AIS transponder is automatically set off my the lifejacket inflation.)

What's the range of an AIS beacon at water level in rough seas? Would it only effectively send when it's data burst coincides with the peak of a wave? And do the yachts have their AIS antennae on the rail (a popular choice), reducing that range further? I always understood that a plb was the offshore choice but I must be mistaken, ARC has requirements for safety equipment.

AIS operates at vhf frequency so is line of sight transmission. With casualty in the water, antenna height is very low. Especially in a lumpy sea, I can imagine that the range of such a device is poor.

Can an AIS transmit if it is submerged, as might happen in this situation?

As I understand it, radio waves don’t penetrate water to a significant extent so any beacon would be impacted by submerging its antenna.
