(edit) The normally understated Holyhead Lifeboat site describes conditions as:"heavy seas .... wind 7-8 sea rough vis poor". Thank goodness all ended well.
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.
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!
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

[/ 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?
