you guys need to google up the JMPBA (Japan) and take a look at the boats they run. I'm pretty sure the JAE was designed using similar numbers and geometry. You'll notice that as the size and power goes up the boat gets quite a bit longer. Granted they run often in much rougher water than we do...
Yup, I really dig that scheme, and just so happens I have plenty of it! my twin will look just like the scale boat with the dots.
What can I say.....a matched set of boats!!
Dave, before you deepen anymore try moving the CG back (add weight in the rear) and if needed raise the sponson angle of attack. sounds like there's not enough weight in the back to keep the prop hooked up. The boat running a neg. AOA will inherently make the boat light in the rear end. good...
