Increase your casting proficiency. Skipping,pitching and flipping.With skipping become good at both forehanded and backhanded casting. Remember your not controlling the boat positioning, the backhanded skip will put the bait were you want it, even though the boater has repositioned the boat.
When in the back of a boat on docks, I'm confident that I'll be able to put my bait further back under a dock than my partner. To areas of the dock that basically don't get hit by other anglers. Making sure that I have new line and a properly spooled reel are keys to being able to accomplish these goals.
Ps And it is always interesting to watch the reaction of boaters when they are waxed out of the back of the boat. Some people just can't handle it well.
