I have a problem, the same as you pointed out, the deck overshoots the bottom of the hull by a 1/4" and I believe this has to do with the laser cut frame? I noticed you showed this in a photo, what I am concerned about is how will this look with hull right side up. I am almost convinced to build as a waterline, then the problem is mute. The upper/lower frame are not glued at this time and I still have that option. I guess one would need to build the frame that comes in the kit to see if in fact that is the problem with the fit of the deck. Did think about trimming off a 1/4" from front of deck, that would not work and create another set of problemswall1. Think I will go waterline on this one.
