OP here. Some interesting comments. Here's my take.
Part of the problem lies in CE classification. The toughest class A says.... 'A Class A yacht ( boat ) is a vessel that is built to navigate the open ocean and surpass a force 8 on the Beaufort scale and surpass waves higher that 4 meters. These yachts are constructed to be self sufficient in hostile seas.'
Lagoon (and other cat) manufactures build their products to this standard, but the standard says nothing about lifecycle. Over time a cat is inherently less likely to survive compared to a monohull.... on an as like for like basis as you as you can imagine.
If you want to travel faster, have a different sailing and living experience then buy a multihull, but be aware that it's lifecycle is compromised. Looking and Ruby Roses YT channel you can see the quality of design and construction in a Seawind. It's superior to Lagoon's, but it's design is still compromised vs a similar size/cost monohull.
On Lagoon's website they say that they have sought the advice of a leading expert company in finite element analysis who have said that a compromised 450 is not dangerous. This is an illogical statement as FEA is done on a known structural design. This smacks of 'hand waving'.
I suggest there have been too many reports of customers having difficulty dealing with Lagoon, including legal action for a wiser person to want to do business with them.
The number of reported similar failures of 450's is statistically significant implying a high probability of future failure. Therefore one might not want to take the risk.
Should of course read “ some “ cats , eg , my , now in its middle age , “ performance orientated “ , ( narrow hulls but plenty of living area ) cat has out lived many similar aged monohulls but I would not be so silly as to suggest it is better than all monohulls .
