ISO 12217-1 Hydromax

Hi,

I am trying to set up the criteria for a small planing vessel in hydromax, I am using ISO 122217-1.

What does the A and n terms represent in

6.2 Offset Load Test - Equilibirum with heel arm

Heeling arm = A cos^n(phi)
A = 0.600 m
n = 1
shall not be greater than (<=) 15.1 deg

also

What are the appropriate upper and lower heel angle bounds in 6.3 rolling in beam waves and wind.

Any help that some one could give me would be fantastic.

Thanks

Ben
