we had pretty much the same thing happen, couldn't find them in the backs of coves, found a few small one's on secondary points. hit the boat docks for a while but only picked up shorts. finally found a pattern with 30 minutes left. Lost a 3 boatside, then got a 1lb 14oz whopper with 5 minutes to go. That was the only fish we weighed. Found the last one's fishing laydowns with a jig.
