Original Dark Harbor
VCG Calculations

The location of the 'Vertical Center of Gravity' is one of the primary factors in Sizing the Sail-plan, Sizing the Mast Column, Calculating the Dynamic Stability Calculations, and Velocity Prediction Calculation that will ultimately determine the success of the Redesigned version of Dark Harbor for aluminum construction. 

Since I cannot find the 'Vertical Center of Gravity' anywhere on the four sheets of Construction Plans, looks like I will be doing a weight study  for the original Dark Harbor design.  I could estimate it at two or three inches below the Design Waterline.  Estimating this most important calculation would not set well with me and  defeat the whole purpose of this writing.

With the 'Construction Drawing', Specfications, shown below, and Computer model I will begin a 'Weight Study' for the Hull Structure, First.
