I did see one of the smev stoves on a Chincogan 52 cat in Pancake Creek, and loved the look of it.
He was having it replaced after less than a month of use as it had steel
and baked enamel bit's in it that could not handle the heat, or the salt environment
This was a few year's back, maybe they have improved.
He also had a HF radio
that had started to die, but I can't remember what brand that was.
The warranty was good, the builder
was doing a 500 mile road trip to sort the problem out, but you'd expect that on a almost million dollar boat.
