I own a Niagara Nautilus 36 which is simply a scaled down version of the 40. These were high quality boats in their time. I have the original instruction manual complete with Polaroids, which is fun to page though. Mine is described as hull #18.
There was clearly a lot of pride in craftsman ship. Most of the original equipment still works great after 30 years. While production numbers must have been REALLY small, the boat was clearly made by folks that made lots of boats. I don't see a lot of the typical production boat mistakes.
Art Epps seems to have been part owner of the company. I have not been able to get in contact with him. I wonder if he is still around.
Henry Adriaanse designed both the 36 and 40.
I'd love to chat with other Niagara 36 and 40 owners.
