the old timer were pretty much a cottonmouth hull that they widened a little and raised the back like that and made the mold, id have to ask dad who got the molds from him when he got rid of them back around 1990, but it looks like they are the same boat i beleive its probably the same mold, ive got a bunch of pictures of some of the complete boats my dad built and ill try to get them on here, i grew up riding on those hulls and always loved the way they looked and performed.
