Like Reeltime mentions, there is a typical migration. There are alot of boats that just follow the charter boats as they are usually out everyday. But, there are plenty of times the charters are hunting and other are catching. Over the years I have lots and lots of waypoints. I use those and time of year. I watch my sonar like a hawk while running towards waypoints as I usually find pods and start to fish where I mark nice size marks while on the way to another spot. Once you build a network of friends you can cover alot more water and/or get upto date info and this really shortens finding the active fish. Site's like this help ALOT also!
