"the lightweight racing yacht – Auliana II is a one-off JV53. "
I thought it was a Rally not a race?

That brings back memories, we broke a steering cable block and then the emergency tiller not far out from the Canaries and the trip back into the swell/wind was a bit tough.
Just reading the report it surprises me that there was no bridle made up to take the towing loads to the main winches? you'd never use deck cleats for taking towing loads on their own! or would you?
I had a bridle planned as a loop from two winches either side to a loop or block on the fore deck which would then take the kedge chain over the bow roller to stop chafing, finally to a large shackle to the towing vessels rope or our heaviest mooring line doubled up.
Isn't that what the ARC briefings/planning/advice should be about?

There are a few boats heading back it seems
a few boats on the ARC tracking site seem to be heading NE?

No wonder the rudder was lost if the boat went over the top of Gran Canaria, as the chart indicates.

But is "the towing line repeatedly pulled deck cleats off the lightweight racing yacht – Auliana II is a one-off JV53. " acceptable ? Seems to me that the boat is badly built. Or maybe that the Spanish RNLI havent read the recent PBO and have just attached the tow line to the cleats.

Or a Bridle back to the Primary winches or mast or both

So they abandoned a perfectly watertight boat..
If they had had no communications system I expect that under jury rig the boat would now be plodding southward to the Cap Verdes, possibly towing warps to keep the stern in check, mebbe with a small headsail and probably with the Mark 1 version of a boom/spinnaker pole jury rudder..when the weather eases I would expect that the mark 2-5 jury rudders would start to be quite usefull.
As would the experience learnt along the way.
Hey ho.

With a deck stepped mast, that would last about 10 minutes.

So they kept on pulling cleats off the deck until they had no more cleats to use!
Thats classic.
Its probably not a case of the cleats not being strong enough for purpose, rather they have been subjected to loads that they were never intended to have in the first place.
Many years ago we ran aground on the side of the channel in Lymington (we had been pushed over to the side by the ferry, and we drew 7'). A very serious looking (as in sea worthy) motor boat came along and offered to pull us off - we passed him a line and he went ahead - and the very chunky cleat on the stern went 'ping'....... we waited for the tide after that.
There is probably no reason why the load on that tow rope should have been any greater than what they would experience when anchoring in say roughish conditions, if they had arranged the tow rope properly.
It should be as long as possible / practicable, perhaps even with a length of anchor chain in the middle to act as a damper for the shock loadings. Take up on the tow VERY slowly, get the momentum going and ensure that the line never becomes dead straight.
And if they had 'pre-tensioned' the bow cleats from the opposite direction using the sheet winches aft that would have been even better (a bit like pre-stressing concrete in a way, by winding up tension on the steel rods before pouring the concrete).

Perhaps a good reason to have a wind vane with an independent rudder for this type or voyage?
