There are several rigs that can be effective for catching big bass off docks. One popular rig is the wacky rig, which involves using a weighted stick bait type worm, such as a Missile Bait's 48 or Senko, rigged on a weedless stinger hook. This rig is great for skipping under docks and can be particularly effective when the bass are targeting baitfish or brim.
Another effective rig for dock fishing is the jig. A half ounce strike king structure jig is a popular choice for targeting docks. This jig is known for its ability to skip well and can be used to fish the high percentage docks that are holding the most fish. It's important to establish a pattern by paying attention to which docks are producing bites and focusing on those.
Additionally, using a drop shot rig with a six inch fat robo worm can be effective for cleaning up any fish that are missed with the jig. This rig can be fished on the outside of the docks to target bass that may be holding in the shade provided by small creeks or trees on the bank.
When it comes to tackle, it's important to use the right equipment. For the wacky rig, a Gamakatsu G Finesse number two weedless stinger hook is recommended to help prevent snagging on grass or light sticks. A 10-pound Sunline Sniper leader is also suggested for added strength when fishing under docks or in lay down areas.
For the jig, a heavy action rod, such as a seven and a half foot heavy action Abu Garcia, is recommended for driving the hook home and accurately pitching and casting under docks. A 17-pound Berkeley tri line 100% fluorocarbon line is suggested for its strength, and a fast reel, like the Revo STX eight to one, can help with quick retrieves.
Overall, the key to catching big bass off docks is to be observant and adaptable. Pay attention to the patterns and adjust your bait selection accordingly. By targeting the high percentage docks and using the right rigs and tackle, you can increase your chances of landing some big bass.
