Here is something that might be of interest in this topic. I have a 45 Roadrunner that always hopped at the strut and lost speed in the straights because of the hopping. I tried all kinds of strut angles, props, strut depths and front sponson angles and could not get it to ride flat without the hop-hop-hop. This version or Roadrunner does not have a flat bottom. Instead the bottom begins to rise a bit from just behind the engine to the transom.
I was looking at my JAE boats hanging in the garage and decided to try something. I removed the Roadrunner's rear sponsons and made a 2" wide ski with a depth equal to the specified strut depth for the Roadrunner. I painted the ski area black and went to the pond. The boat ran very well with no hop! The other thing that I found was that I could launch much bigger props than I had ever launched before. The bigger props were not always faster, but they launched and ran allowing me to optimize for the best prop. I am running a CMB 45 VAC in this boat with a Bouchie pipe. I am not sure what this means in general, but for my particular 45 Roadrunner the wide ski seems to have transformed it into a better boat. We have a Crapshooter 45 that runs great with rear sponsons...so who knows? Just thought you might be interested in this experiment.
