It's not a bug it's a feature! The carrier operates in the same frame of
reference as aircraft - it has to otherwise you couldn't catch wires
correctly. Unfortunately, the sea surface does not - elsewhere on the sea
surface you will see the carrier up to the sponsons in water. If you don't
crash into the sea near the carrier you won't see this bug (er ... feature).
I have a partial fix moving the wake to compensate, which also uses
submodels to provide a nice curved wake following the carrier as it
manoeuvres. But since it uses the scale animation to work, and that's broken
for submodels in plib, I haven't uploaded it to cvs.
Hope this explains it. You will also see the same effect when moving around
KSFO with an aircraft, although much less, and you will have to look very
closely to see it. BTW - this isn't a new problem it's been around a while.

Could be a joke unfortunately it is not.
It has been checked, that is not an offset error within the 3D model
definition.
I guess, It is a zero level calculation bug regarding moving models (AI) on
the sea.

It would be great if someone involved in this aspect of the code would be
willing to dig in and figure out the problem before the final/official
0.9.11 release. My worry is that if there are not enough developers
concerned about these sorts of problems, we will not have a very good
release experience this time around.
I do know that the ground intersection code is completely different between
OSG and PLIB so something must have fallen through the cracks on the plib
side.
Thanks,
Curt.
