Eggman, you might want to call West System's tech department and discuss the crack with them. (You pay for the call, the support is free, even if you haven't bought anything yet.)
I would be concerned that the crack means the deck was really stressed or impacted, and there is damage to the fiberglass in a larger area around it, i.e. extending for several inches on either side of the crack. Maybe it is ignorable--but they might suggest cutting it back and bedding in a new section, rather than gambling on it.
It can look perfectly good on the outside--but the glass fibers may be broken inside.
