I saw that on the bbc site earlier, I quite expected it to be a wharram with the roped up hulls, that looks a great deal more modern in underwater profile.
Will be interested to hear the outcome, a designer / manufacturer somewhere has been locked in his bog all day no doubt.

I've sailed round Holyhead a fair bit and can say that whatever the sea state anywhere else you can double it round South Stack.
For the cat lovers, you can see that nature abhors 2 hulls lashed together.

No one on board wearing life jackets - and the Holyhead lifeboat describes the sea as rough.... I think they where very lucky.

And their 'liferaft' appears to have been an inflatable dinghy - Very lucky indeed.

As far as I can see it didn't sink +10 for cats /forums/images/graemlins/smile.gif

'The coastguard said the 46ft yacht had a slight structural weakness......'
A case of British understatement, I think!

Had visions of a pussy cat, with a boom dropped on it split in half and thrown over the side! /forums/images/graemlins/laugh.gif Now that would have been a picture for a caption!

What make of catamaran ?
At least Wharrams designs cater for shock loadings and unequal loading on hulls .
and
Others of rigid designs fail when bending moment/ shock load on crossbeams encastre fixings result in stress concentration and fracture . Only need a slight tear in the joint for brittle fracture to occur. Could also be caused by poor lifting arrangements during haul out

One hull good - Two hulls better, provided firmly attached to each other! /forums/images/graemlins/laugh.gif

My dog says you're psychic - that's exactly what he was thinking.

[/ QUOTE ]Does that describe sea conditions at the time when the picture was taken, or did conditions change in the meantime? Judging from the pic, the most scary part is the colour of the water...

[/ QUOTE ] Off South Stack the conditions can change from those shown to much bigger seas and vice versa as the tidal flow changes.

Catamaran - two unseaworthy boats joined together to make another one? Or was this one trying to reproduce by binary fission? Or had the rudders been wrongly connected so that it tried to turn both ways at once?
