Okay, the gear and line class are fine. I have caught dozens of halibut on 12# monofilament main line on Abu 6500’s.
I have also caught 36” halibut at Paradise Pier on frozen bag anchovies on a C-rig consisting of nothing more than a 3/4 ounce egg weight. The rod was sitting in a holder straight down, the anchovy was threaded (head down) on a circle hook and suspended two feet off the bottom. The fish self-hooked and loaded the rod off a couple pounds of drag. Make sure you have some good quality bag bait like the Sport with nice big jack anchovies. The Sea Wave is too beat up sometimes. I’ve out-fished people using shiners this way. Some times the fish are keyed in to smell (over vibrations).
If you get to your spot it is worth taking a little time to catch some baitfish on small hooks (size 10 or 12 bait/holders) baited with small pieces of market shrimp, squid, anchovies, or pileworms. Shiner perch, smelt, and even bullheads will work for halibut. Your odds increase many times as your live bait doesn’t get consumed by crabs and big smelt while waiting for halibut.
Also, you might try a slip bobber rig above your threaded anchovies (or 2 hook mooching style/trap-hook style way of baiting anchovies [one hook in the head/one hook in the tail area].
If you can set the hook when the fish is running, always better because you know there is tension on the line but not necessary to set hook. After the initial pull, and possibly a short run and stop or not, the halibut is usually sitting on the hook. You can always give a medium swing upwards which many times results in head shakes in return and fish on! The more opportunities, the better you will get. I have caught many in the past ten years where I just went for my net and let the halibut load up the rod and self/hook stripping drag out on light-wire circle hooks.
Good luck!
