Well is the part unanchored at all?

btw this should be in help and feedback not development discussion.

It is unanchored. I will try to move the topic.

No, do #help-and-feedback:building-support.
I found this it might help:

Why don't parts move with waves?

Even if the waves show they’re moving, they’re like client effects, faked and do not effect the object in any sort of way. Imagine it as a brick with effects slapped on. If you want to get continuous bobbing effects, slap in a force that pushes it up constantly like bodyforce, that should retain its bobbing motion yet not effect physics too much.
