Comparisons between Facilities

• Model Length, L:

IIHR = 3.048 m

FORCE = 4.002 m

INSEAN = 5.72 m

• Normalized model length, L^* = L/L_IIHR:

IIHR = 1.0

FORCE = 1.31

INSEAN = 1.88

1. Sway derivatives

Velocity	Acceleration

2. Yaw derivatives

Yaw rate	Yaw Acceleration

3. Summary

• Sway derivatives are nearly independent on model size

• Yaw derivatives (particularly yaw acceleration derivatives) exhibit considerable dependency on the model size.

• General conclusions for non-linear derivatives are precluded as the data exhibit large scatters in the comparisons.
