RE: 3rd boat. flat deck 3-point hydro
How about contacting Self-Inflicted or even looking at his site and info he has typed cause you've put your heart into this project. You can't stop now, i said so,LOL!! ?, are you by any chance going to use pink foam inside the sponsons and cover with 1/32 ply? Why i ask is, years ago i built a 25" Cat of Jay Turner and used pink foam inside sponsons with 1/32 ply and worked great. That's when nimH were in play and added weight but i was a novice and only one boat site around at the time. Trial and error and just reading everything available to gain knowledge. Well, have a good day. BTW, Jays sponsons were 25" long and 2 1/2" deep and wide.
