clunc from my hobie 17 hulls

hi all,
i was able to separate both hulls from the beams and now i have the hulls in my garage.
I hear cluncs from both hulls when i flip and roll the hulls.
Can i suspect any styrofoam blocks inside that cause this sound?
If so, is it common? What can i do about it?

It is likely the foam blocks inside the hull. They are located behind the centerboard trunks and are there to keep your boat afloat in case you get a hole in the hull.

You could also be hearing the centerboards banging around inside the wells. Either way, it is not a concern.
