Pro Water - Matching Rotation

Hello, I'm trying to make a sailing ship on Pro Water (Water4) and I am trying to access the Gerstner Displace Script so that my ship can match the rotation of the waves. I am trying to achieve the illusion of having a ship float on the water without actually doing it.

The Gerstner Displace settings are what is used to generate the waves within the pro water but I am having a hard time accessing the variables.

Incidentally, if there is another way to achieve the same effect, I am all ears.

Thanks in advance.
