1.  Resistance coefficients are based on wetted surface area (S/L²) =0.2682 with rudder for static orientation in calm water.

2. Comparison Error, E%D = (D-S)/D×100, where D is the EFD value, and S is the simulation value. 

3. Relative change in solution: ε₁₂%S₁ = |(S₁-S₂)/S₁|×100, "1" refers to the finest grid.

4. Iterative uncertainty U_I is based on fine grid solution.

5. is the theoretical order of accuracy = order of convection scheme.

6. U_G is the grid uncertainty. is the simulation numerical uncertainty.

7. U_D is the data uncertainty.

8. is the validation uncertainty.

9. Brief details of the V&V method should be provided in the paper (including the determination of U_I ).
