Botttom Coat Question

Playing the devil's advocated I pose this question:
If I gambled and tried to get a third summer out of my anti fouling coating and some/most of it wore-off by mid summer would the barrier coats that were applied before the antifouling protect my hull from water penetration?
Advice appreciated
