i've been very interested in building my own flat bottom boat. i work at a Ranger dealer and contacted my ranger sales rep which is also an xpress boat rep on building me a 2472. aluminium is ridiculous right now, but someone said they had a 20 x 8 marine grade .125 sheet which they were building, if you google what i just said you can read the thread, and his boat is amazing. a 25 ft break is real hard to find, unless you know people (mirrocraft is in gillet, wisconsin) but its still hard to get them to do personal chit, even when they know you. i say go for it, and let me know how you do....! there are a couple of guys that make air boats on here which could make a wicked pusher boat, but its gunna cost you...
