A: Woods calls for 600/300 glass over Okume. Assuming the same weight of resin, that's 1800
B: I used 5 pound foam core, which I believe is H80
C: Woods calls for 900 GSM each side, and I assumed another 900 GSM resin for a total of 2700 GSM and added the GSM of the foam itself for a TOTAL panel weight... For some reason I get a higher number this morning (3717GSM)
D: I didn't use Rob's number because I was using Richard's number........ Richard is the designer of the boat in question.... I will go by his figures by default.
I couldn't find the original text in an editable form easily, but I had saved a screen shot along with a note in red by way of explanation in a folder. I've included it below. Hopefully it will come through.

Question A) Regarding your 9mm Okoume layup, how did you get to "Glass and resin total 1800 GSM"?
Question B) Regarding your 12mm Divinicell layup, did you assume H100 for core?
Question C) Regarding your 12mm Divinicell layup, how did you get to "Glass and resin totaling 3600 GSM"
Question D) Why did you not use Robs 1400GSM for your 12mm Divinicell layup?
