Roger Weiman retired to lake havasu a couple of years ago. He sold the molds to a guy in so.cal who hasn't done anything with them. I think Oldrigger told me that Roger tried to build some new boats for his friends from the molds but that the guy who owns the molds is being a jerk and won't let him do anything with them. If you like the 18' Bonneville then you can get a new one from Advantage Boats. Their 18 is identical to Rogers 18'.
Their are used 19's around you just have to look hard to find them.
