Hey Joal,
I had intended this to be posted with the pictures above. For some reason this post is whippin' my arse today. Pics are just the reverse order of what I wanted:
I received your PM, and no, I do not sell plans for my boats.
I would suggest that you purchase a paint plan from David Newton (www.newtonmarine.com) of a particular hull you like. This will give you a 1/8th Scale three view for the hull of your choice. Determine what size hull you want to enlarge that 1/8 paint plan by that percentage at a local print shop. Make any changes you want - possibly hull bottom positive angle of attack; sponson shape and angle of attack; change other measurements to suit your needs and start cutting the following pieces: Tub sides, transom, nose block, and determine what width you want the tub to be and cut a couple spacers/bulkheads. Sponsons: Inside, and rear sponson plates. Basically what you have now are the major plywood pieces to build an outrigger. Add some Styrofoam/foam to fill in the voids for the center hull and shape that. Build a set of sponsons as you would for an outrigger. You now have the basics for your new hull.
My CT is 49" long, 25" wide, after plane is 27 1/4", Tub is 16" wide at sponson rear plate, tunnel width is 13 1/2", transom is 11 3/4" wide.
Make sure you check the rule book for the sanctioning entity you plan to race under. In the US, there are two separate sets of specifications for Classic Thunderboats - both similar with a few differences.
Good luck. When finished you'll have a distinct boat of you own.
CHEERS !!! Bob
