The sandwich construction of Starboard (taken from a SB 161).

During a "slowly catapult" with an all new SB 161 the sailor succeeded in placing his foot under the mast in an attempt to minimize the damage.

However, now the foot went though the nose of the board, and further more the sailor damaged his toe nails.

Here the sick area  has been removed (you might recognize the outline of the ball of the sailors foot), and to make the sandwich construction more obvious the edge nearest to us has been sanded chamfered.

In this close up you can see the thin veneer on top of the sandwich construction, and between this and the "distance layer" (from PVC?) there's probably a thin layer from glass weave. In the nose of the board (to the right) the construction is further strengthened with a layer of aramid fiber weave ("Kevlar"). Lowest, next to the foam (not to be seen here) there's a layer (or a couple of layers) of glass weave.

I don't know for sure if the resin is in fact epoxy. At least the typical smell from epoxy isn't very dominating when you sand the glass weave.
