The Niagara 40 PH is not of the same line as the Niagara 31/35/42. They are Ontario built, but not, I don't believe, by Hinterhoeller.
There's one listed in Vancouver now too, and I know of one cruising the Caribbean chain. I believe there was a mid 30 foot version produced as well, one of which is in the Victoria area.
