I am late to answering this question but maybe for next season.
You have a whole lot better chance of winning if you can pre-fish a given body of water a few times before the tournament dates. Get a good quality topographical map if it is an impoundment or a chart. You need to see depth contours and structure.
Plan your tournament day strategy. A "game plan". Plan in detail exactly where you plan to fish and how you will do it. And plan several areas or spots and how you will fish those. Many times the fish were there the day before but will be gone the next. Plan your strategy for changes in the weather. It happens. What lures, baits etc. Have those rigged on the rods the night before or before you start the tournament. I have fished tournaments where it was as simple as who ever made the most casts in productive water usually won. Productive water will be determined by species, season, water temp, life cycle, available habitat, food source, etc. Have everything organized and ready on your boat.
I could give you more information if I knew the species, the season and the body of water type.
You have given me ideas for a hub or two. Thanks!
