This new diamond though is just bedded in the bottom of the core with no divinycell and the bottom laminate is attached just from the resin around the edge of the plastic diamond? Am I missing something?
That's how I see it as well. The diamond plate is inserted in the foam core the same way the footstrap inserts are on the deck side ...router hole + resin ..... in the EPS.
The insert (plates) are waiting under the deck upside down to welcome the 4 screws of the strut plate (numbered 1 to 4)
So, it is mostly the surface tension along the deck skin that holds the strut plate in place, providing the EPS around the diamond plate remains dry and stuck to the upperskin
and that the hull diamond cut laminate does not unstick under the push/pull or torsional load.
If water finds a way through the router cut via the board bottom .....
.... The Performance board has a 3-year warranty
The Performance board thickness is +/- 5cm (2in)
