Barry here are the steps I would use:
1. Use 3 design variables to define the boat position with respect to
the water line (i.e. Vertical boat CG location and Angles about x and y
axes) .
2. Find the CG of the displaced volume and its distances from two axes
(i.e. x and y)
3. Write a relation feature to express three equilibrium equations
(i.e. sum of forces in vertical direction and moments about x and y)
4. Use an optimization feature to find the 3 design variables that
satisfy the equilibrium equations (i.e. minimize abs(sum of forces in
vertical direction).
If any additional information/clarification is required don't hesitate to
call or email.
