new member with Mod-VP tunel hull questions

Hi there

New to the forum and had a question that I was hoping to get some insight on from the vast fount of knowledge and experience here

I'm getting ready to build a small plywood on frame outboard runabout with a low-deadrise warped bottom design. I will be converting the design to inboard jet drive utilizing the powertrain from a 2004 Honda R12X PWC - 12' 6" hull length with a 5' beam and I will be adding a drive extension box to the transom to move the jet pump assembly back about 18" aft of the transom.
I recently started to seriously think about modifying the design into a Mod-VP style tunnel hull with center pod (similar to the Southwind Tunnel Dragster or Placecraft hulls that were popular in jet drag boat racing circles, which were the models that I have drawn from for this project)
I have a pretty good idea on how to incorporate the tunnels into the build but I haven't been able to glean much info pertaining to appropriate dimensions of the tunnels such as width, depth, angles, etc....

If anyone has any resources or experience that might help me with this issue that would be greatly appreciated!!


Thank you in advance
Dave

Hi Jim, thanks for taking an interest in my little bit of insanity

It's funny, but I actually found your Aero Marine Research website right after I posted my question and it looks like the wealth of information that you've made available has exactly what I need to get this project rollin.
I really appreciate your offer to take the time and help me with my project Jim. Is there any particular days and times that would be better to contact you? or which materials that you have available that you can suggest to get me started?

Thanks again!!
Dave
