Thanks Kim...I did read post # 17, however your explanation makes absolute sense...
With respect to dimensional variance, the transom plate appears to have a little [plan view] curvature ...so unless these plate tapping's/holes were CNC cut, a natural dimensional error would inevitably creep in with physical paper/plastic templates being used
All in all, the visual quality of the models and the attached equipment as shown is outstanding & I am not sure the human eye could perceive such miniscule dimensional placement differences between vessels
Keep the images coming
