oooh, so it was the pressure of the water pushing inwards?

So Wolfy now that you have joined the Proa squad with your new taking Proa will we see you up at Arkles Bay next year promoting the breed?

 

Hey Squid I think you should offer a bottle of rum to the newest member of the Proa squad..

Sorry to see the wolf this way up Tim. We didnt have much luck down in tauranga, all five cats fell over more than once. one crew member got left behind, an A division boat picked him up floating down the harbour. I think 40 knts was a bit much! My crew fell through the main as we pitch poled and f...k it big time .Try, try again

That is just the saddest sight! Hopefully not too much work to get her sailing again.

 

Looks like its going to be at least 3 months before wolfy is sailing again

Jeez sorry to hear that.

 

When we were bailing the guys were saying that all you needed was some expanding foam to fill the hole and you'd be out there for the Simrad!

if they righted it end over end then the arse would have sunk down when the bows came up, pressure built up in the hull then finally.. POP!

 

 

Wrong Jordan.

 

This was a compressive failure, we know this because the break is inwards.

 

Not an outward explosion like you describe.

 

There is a risk associated with "egg Shell" methods of construction such as Tortured ply, this is what happens when they fail.

 

 

If the hole were due to the pressure difference, it would be an inward break would it not.? Plausable explanation i think? I would never have expected a hole such as that, cracks and splits sure but that hole is interesting. I cannot work out how you would place those two surfaces under sufficient compressive load to do that damage, with out completly rooting the a fair bit more. Or to ppl who know, is that a familiar type?

 

Good luck with the repair.

What water pressure ?

 

The rope load is in excess of at least 6 tonnes due to the type of ropes they were breaking.

The beam (bridle attachment point) is only 2 metres infront of the boats centre of buoyancy (pivot point).

 

the way it failed is classic compressive failure, the hole you see on the site is only a baby compared with the outside.

Would the Farrier type of option have worked where you flood one ama and bring her up sideways?

The way i see it is there have been plenty of mulit's to flip:

 

Silver Raider x 2

Tigre X 1

Attitude X 1

Hard Drive x 2

Frantic Drift X 1

U2 x 1

Exodus x 1

Roxanne X 1

Timberwolf x 1

This way Up x 1

Dirty Deads X 1

Te Kuiti X 1

The GBE that tipped twice in one two handed race..

 

My solution would be to have an upper limit of breeze that these craft are allowed to race in, say 20 knots limit and the 1st reef in at 10 and 2nd at 15, this should slow new members joining the UDC club.

 

I hope my memory is correct, hate to offend anyone.

Please feel free to add to the list.
