Zack Taylor Wigeon modifications

I'm thinking of building another Zack Taylor wigeon sneakbox but would like some opinions on some proposed modifications. I'm thinking that instead of tapering the boat back to the stern, leaving the width at 46 1/2 inches wide (mold B which is 5'1 1/8 " from stern) to the transom (total length of boat is 11 ' 9"). I would also leave the height of the finished side planks the same from mold B back to the transom. Also, I would alter the V bottom from a ratio of 8" to 1 1/2" from mold B back to something with less of a V (flatter). This will result in a deeper and flatter boat in the stern that should be able to plane. How would the sea worthy capabilities be affected (I love my current one, but it isn't fast enough with a 6 hp)? What would be the resulting requirements for power be (maybe 9.9)? I like the build process of the boat and would like to build one that is capable of covering more ground faster but still be very stable. Any opinions or comments you guys may have would be appreciated. Thanks!
 
I haven't had time to pull out the book and see the mod you are suggesting. It seems you will need to keep the keel going flat back by deepinging the aft frames. I have thought of similar modifications to other boats. I would keep all the forward rocker and lose everything where it starts to rise in the rear.

If you want to keep some seaworthiness, I would keep the V. Not flatten it. Deep V's still plane don't they? Although you will lose much of the seaworthiness by losing the rocker anyway. It simple won't perform the same in the chop. Go fast or go safer. Maybe you hould consult with a few real boat builders/designers.

A longer displacement hull will go faster. Not much but some.

A good comparison might be the Devlin boats Compare his smaller displacement vs planing hulls. maybe even order his study plans of the planing hull to get a better feel of the changes needed.
