I can't say for sure.....
but it looks like this was one of the early designs of the Runnerbottom. I can see were a couple pieces of Masonite might have been thrown in the bottom of the mold to create the hull design. Then later on a new mold was made or purpose built for the Runnerbottom design. One of the neat things about this hobby is that a lot of the history of this sport is still floating around and you can see just how designs have progressed over the decades.
