I wondered the same thing, but in regards to the Centerboard fill on page 52. The mix looks dark like it would be mixed with wood flour instead of Silica. I emailed CLC and was told that it is Silica, but that the photos make it look darker than it actually is. I'm using Silica mixed epoxy for all bonding of wood to wood. That's what the manual says to do (p. 9).
The wood flour seems to be reserved for fillets.
