When targeting big bass off docks, there are several effective rigs that you can use. One popular rig is the wacky rig, which involves using a weighted stick bait worm, such as a Missile Bait's 48 or Senko, rigged on a Gamakatsu G Finesse weedless stinger hook. This rig is great for skipping under docks and can imitate both baitfish and brim, which are often present in those areas. The wacky rig is especially effective when the docks have a little more depth, like in the back or side of pockets, where the bass tend to hang out.

Another effective rig for dock fishing is the Texas rig with a big worm. This rig is versatile and can be used for flipping docks or fishing deeper areas. For flipping docks, you can use a 7'3" to 7'6" heavy action rod with a 5/0 or 6/0 offset hook and a half-ounce weight. The weight should be pegged to fall quickly and avoid getting caught in brush piles or other obstacles. This rig allows you to accurately pitch and cast under docks, where big bass often hide.

In addition to the rigs mentioned above, it's important to have the right equipment for dock fishing. A heavy-action rod with a little bit of tip is ideal for driving the hook home and being accurate with your casts. Fluorocarbon line in the 17-pound range, such as Berkeley Trilene 100%, is recommended for its strength and invisibility in the water. A high-speed reel, like the Abu Garcia Revo STX with an 8:1 gear ratio, can help you quickly reel in big bass once hooked.

Remember, when fishing around docks, it's crucial to be quiet and stealthy to avoid spooking the fish. Focus on fishing the key features of each dock rather than trying to cover the entire structure. By refining your bait presentation and targeting specific areas, you can efficiently cover more docks and increase your chances of catching more big bass.
