I like these long slender fast passage makers, or whatever you want to call them. I like the idea of being able to go 10-11 knots instead of 6-7, but still be able to take big seas safely and recover from a knockdown, unlike a power catamaran. Plus, I think they look cool. If I was rich I would get myself one! But I like "different".
And just because it's different and strange looking doesn't mean it's a bad design. To me, it makes sense to reserve any criticism that it's a bad design until you have had some actual time on one.
I don't know sh&t from Shinola, but I like learning about new things.
