Than can be tricky. The odds are high that the delam is caused by the area
around the mast track softening up allowing the track to "work" and fatigue
the skin and reinforcing layers under.
In my opinion the right way to do it is to rebuild the area around and
under the mast track after removing everything that is soft including the
track itself. What specifically is needed depends on the specific
construction but in general, carbon fiber, fiberglass, epoxy (like West
System) and a replacement track like one from Chinook that can be bedded
from the outside (molded epoxy boards usually mold the deck around original
mast tracks and doing this in a repair can be tricky) would be used to
create a new reinforced skin, bonded to the foam core, to carry the track.
Remeber in a molded epoxy board the load of the track is carried by the
skin, so it has to be strong. There are no stringers like in a foam core
polyester board to bed the track into and distribute the load.
