I think the amount of work that goes into making a Wriedt fast and stable exceeded the amount work most people were willing to do.
As far as a lake boat goes, they are pretty solid.
I grew up in a 16' o/b stinger and they are everywhere!
Not much if a story to tell.
There were hundreds of boat builders and maybe 10 original molds they were all being popped out of.
