Conventions
- Coordinate system for comparisons is fixed to
midship, undisturbed waterplane.
- All quantities non-dimensionalized by density (r), ship speed (U)
and length (L)
- All CFD predicted force coefficients should be
reported using the provided (geometry and conditions page)
wetted surface area (SDWL). Force coefficients defined as follows.
