Avi-Toon Boaterhome help needed

Hi all,
I have just finished building a 24ft pontoon boat with a gutted 17ft Avion campershell mounted on it. I tried just the two 24ft ..."D" shaped pontoons and they were fine until I added a little too much weight inside. So I added one thrid 20ft round pontoon in the center...this pontoon mounted about 4.5 inches lower in the water. It did pretty well but the back of the rig was a bit too low for my taste. So I built a set of tracks and slid both 20ft round pontoons under it....now it's a fourtoon....I have all the floatation I need and then some...now the center pontoons are taking most of the weight....lifting the outer ones up....but there is too much water wake problems between the hulls...they are too close together...but it works...I kinda plans off with a 60hp Yamaha 2 stroke...apx 15mph. I like the faster speed "when needed"
I think the only way I'm going to be happy..is to build my own hulls....I would like to keep it a two hull design....Because I originally had a trap-door in the rear floor with swim ladder or used for a fishing hole. I would really like to build a planning hull design with a slight "V" and go as wide as possible and go high enough to give me some freeboard for wakes hitting me. I have pull out walk boards on each side with hand rails...so the tops of the pontoons need to be flat. I weld alum awnings for a living and have a really nice BIG Miller Mig..I think I can buy most materials for around $2500...but not sure what thickness to get 1/8th or 1/16th? I guess the thinner I go the more bracing I will need.
Anyway I am not a boat building pro and need a little help with this design...I have photos of the Rig but no weights so far... My guess is around 3000lbs Max.
Anyone willing to get involved with some advice?
Bud
