I just noticed that carve rocker series have DFS system fins, patented by Zeboards (Asian fabric).

They also have strong epoxy boards.
Check the board test video.

Is Naish new construction produced by this company?
I already rode this boards, nice flex but the shape available is not enough loose at high speeds (wide tail).
Strong boards but can't hold heel dents.
So i'm presuming Naish added wood on top.
Btw you can buy this boards in Europe for 350€.

Good winves
