In the summer I like to find areas that have little to no pressure on them. I know thats hard to due for most of us in south Florida, but very doable.
Some folks say scale down on the size of the bait, work slower.....I say scale down on the size of the boat and work tighter. Try getting into areas that the bass boat will not go. Use google earth to find the remote and hard to get places. I know thats not doable for most, but the lesser known and out of the way areas can be highly productive in the summer.
Another strategy is to try some night trips.
