Are your inflation layers moving along with the ship? I would suggest separating the boundary layer zone from the main fluid and assigning a passive rigid body motion to follow your ship.
To do this, create a Boundary cell register for the inflation layer:
Then separate the newly created cell register from the corresponding fluid zone:
Finally, in Dynamic mesh zone settings, set the inflation layer zone with rigid body motion with 6DOF set as passive. Select the same motion as for the Ship.
