You would be better off with the 30" length, 6" of tunnel width, 1 1/4" sponson width, 15 degrees of sponson angle. Plans for the JD WOF 28/30 are available from RC Boat Modeler Plans Service.

I agree with Jerry for the most part.

30" in length
15-17 sponson angle
12 inch ride pad
6.5" tunnel width
1-1 1/4" rid pad width
3/4" tunnel depth.
40 degree non trip
10 degree top sponson angle
19 inch center section length

That should get you a good fun boat for a .21

Or you could just buy a set of Jerrys plans.... Much easier, and takes the "thinking" part out of it.

If you go the plans route, my [link=http://home.earthlink.net/~obwof/]WOF Build[/link] site just might give you an idea or two on how these are built.

To save a lot of hassle in designing one that might work you're better off getting the plans from someone who knows what he's doing. You will save a lot of time and not waste money on wood and other materails.
For wood in Texas, try Lone Star Balsa. I've heard nothing but good about this business.
