I was on the 440 and it was pretty nice. Seemed like they could have used a bit more wood and less plastic - though I got lost a couple of times and needed a map to find my way out!!
I do not know if I am totally set on a catamaran. Still educating myself. I will likely charter one in the near future. But for a half million, I would likely look at other boats too... namely a Nordhavn. But, the technology they are using is very neat. It could be applied to a trawler too.
If they could improve battery technology and solar technology, it would revolutionize the marine industry.
