Preston, a few dock rules.
1. Bass like to hide and be under something to feel safe and wait in ambush for an easy meal. Docks allow this to occur.
2. Bright sunny days are best for docks as the bass will be under them as stated above.
3. Cloudy days allow the bass to roam so docks are just another target but maybe not the best target.
4. Docks close to deep water are the best.
5. Docks built close to the water are best.
6. Docks with grass, brushpiles and fishing rods on them are the best.
7. Skip plastics under the dock with a spinning rig to avoid backlashes.
8. Throw plastics all around the dock, starting in the front and working back to the shoreline.
9. Concentrate on any grasses next to the shoreline.
10. Concentrate on any lily pads around docks.
11. Concentrate on any wood (blow down trees) around docks.
12. Hit as many pilings as you can with your plastics before moving on. Hit them a number of times and from different angles.
13. Throw your crankbaits and spinnerbaits and Chatterbaits, etc. parallel to the sides, in front of the dock, and all around the dock.
14. Throw the moving baits many times before or after you throw your plastics.
15. Throw your plastics on a Texas rig, a Drop Shot and a Shaky Head.
16. Skip your Senkos or YUM Dingers rigged wacky under each dock. Throw them at least five times each.
17. Throw your Senkos or YUM Dingers all around the dock and hit all pilings.
18. Throw your moving baits in between the docks from the shoreline back to the boat when moving from dock to dock.
19. Consider throwing your jigs and pigs under and all around the dock
20. Approach a dock quietly and from the side.
21. Try to use your trolling motor as little as possible and be very quiet.
22. Have the net ready to roll without much movement on your part.
23. Fish each dock to the fullest before moving on.
24. On a day when you want to study the docks take your boat and troll all around them while you view your electronics to see if you can spot any underwater structure, holes, drop-offs and if there is any deep water nearby.
This information is just for starters. If you do catch a bass do the same thing over and over and over again and again and again as you have found the pattern for the day.
All the best.
