So a bit more information. Supports my theory of major rigging tension loads on the hull as the starter.

The new info is that the hull was reinforced up to the forward end of the cockpit, and stopped there. Definitely a stress concentration point.
It is also clear that it was only the main cabin area which was initially flooded. The watertight bulkheads stopped the initial flooding from reaching the fore and aft ends.
So my theory is that there was some kind of slow leak from the engine area, and this was confined to the main cabin. So when Tapio woke to a crack noise, the water in the cabin was already up to his knees. This weight in the centre of the boat, caused more sagging loads, (bending of the ends upwards) adding to the rigging sagging loads. This probably caused a crack to occur in the bottom of the hull at the stress concentration point.
Why would the hull crack? A lot of work was done adding bulkheads. For glassing on old surfaces, usually a solvent is applied to key the surface. Maybe a combination of age, fatigue, solvent, stress concentration, and all the tension loads was just too much...

Tapio said that as she sank the rig still looked tight. A long crack only centimetres wide can let in a lot of water. The genoa was still drawing, so it would pull the forestay out, and that can keep the rest of the rig looking tensioned.

Thanks Ramona, for your pics of the Aries. Can one still buy one?
But could you tell us about your vang?

The Aries is still being built in Amsterdam. Mine was made in Denmark and the originals where built in Britain. The British made ones are imperial where the others are metric. Still plenty of secondhand ones around and parts for both imperial and metric are readily available. There is a good group page on Facebook and of course the home page.

Interestingly in both the GG races the people using Aries used secondhand ones and in some cases never had them serviced first.

My boom vang is a fairly conventional arrangement but with a boom strut to support the boom while reefing. It's laminated timber with lay ups of epoxy and cloth, some carbon fibre to reinforce the ends.

Thanks, Jules. I have contacted the seller.

Cheers,

Be mindful that before departing with your cash,, there are boat owners out there that are willing to get rid of the demon that they have perched on the transom for very little.
I gave away ( for nothing) a Fleming Major and a Navik because I was sick of them cluttering my shed. I bought an Aries for $400 which is what I currently use. Windvanes are out there for a carton of beer,,(but not that craft beer stuff)

Seller is going overseas on Tuesday with "no immediate plans to return" so both time and price seem to have brought the process to a halt.

Down to 4 competitors in the GG.

Certainly not what I would have expected with such solid boats but cutting competitors off for being too slow doesn't help.

This time the self steering gear failure is with a Windpilot!

Abhilash TomyOfficial Called #GGR2022 at 0852UTC to advise Failure of his Wind Pilot self steering gear and that he had used up all his Spare Pendulum Blades in previous failures. At 0852UTC he confirmed he has lashed the tiller and is now considering all options. At 0405UTC GGR had given Abhilash his position and a weather forecast as he was sailing along a LEE SHORE with increasing winds over the next 24 hours. This is that forecast.....You 15th at 0400Z 52. 41.68S 76 32.75 W 0700Z SW26 G35 S4.2SW 1300Z SW30 G40 S4.9 1900Z S31 G41 S5.6 16th 0200 S23 G33 S4.8 0800 SW14 G22 S3.8 good luck! The GGR tracker was set at hourly at that time. He has requested no assistance and is in control of the situation. GGR will update as more information becomes available.

Very interesting duel between Abhliash and Kirsten right now.

If you click on the Overlay Map Flag (Wind) icon and choose WINDY, you ill see the weather that they are up against.
Abhliash is turning NNE and so has Kirsten.
Check out there relative positions to the prevailing winds.
Like slow motion chess.

UPDATE - Ian has made contact with GGR - Puffin rolled, she is dismasted, he has injured his back and it's hard to move, there's 2ft of water in the cabin, the situation is worsening and he needs a weather break to cut the rig free...we are waiting further updates via GGR from MRCC who are coordinating the rescue - we're all with you Ian

You can have all the modern stuff and still get caught out in bad weather eventually if your offshore long enough. This bloke had to pull in behind some islands to make rig repairs a couple of weeks ago. The weather was bad but I'm thinking the same rig problem re appeared.

Seems like the GGR has put a dent in the Trade wind 35 yacht fleet, that is two that have been rolled Demasted and scuttled
