Rick,
Look like a nice program!
I would go with full displacement (2000kg), the lw hull will support about 700 kg of weight at that displacement.
The righting moment is about 6 ton*m.
For the height of the CoE, I am not sure but I am planning to go for 50 sqm of total sail and 12 m masts (so 25 sqm per masts), with a root of 3m look like a CoE around 6.5m above water
So 10 sections of 750mm from stem to middle, x value for the middle of the block.
x=375 mm v=0.046 m3
x=1125 mm v=0.123 m3
x=1875 mm v=0.180 m3
x=2625 mm v=0.220 m3
x=3375 mm v=0.244 m3
x=4125 mm v=0.252 m3
x=4875 mm v=0.254 m3
x=5625 mm v=0.233 m3
x=6375 mm v=0.217 m3
x=7125 mm v=0.216 m3
Thanks!
