experience / history of Triton submarine

I wonder if any of you has any experience or heard about the Triton submarines of US Subs/ Triton Subs, a US manufactorer of classed yacht subs.

They seem to have been around for a very long time but I don't see many pictures of actual subs that were built.

I saw them at FLIBS last week and it looks like a smart design but I wonder what others think about this manufacturer.

Did you try a Google image search?
Seems to be a few images posted on net:

 

Sure, those are the same the manufacturer puts out. But I see no pictures of a 3-seater and from what I can find online it seems only 2 subs were actually built.

I guess my real question is: why does a company that has been around for so long and apparently builds a quite ideal yacht sub only manage to build two subs?

Am I missing something?
