Re: California Halibut
IMHO spreader (made from wire clothes hanger), weight on short arm. 18" leader, 4" Dodger, 24" leader, 6" wire leader, circle hook with 6" white squid or bucktail. It's as important to know when to fish for them as how. Best July, Aug. and and starting two hours before high tide.
Here in San Diego, the water's not quite as cold as up north, so the season's a bit different, best times here being Oct to Dec, then again from Mar to May (I'm told these are the spawning seasons here). Jun through Sep the water in the Bay is too warm for good halibut fishing, and Jan-Feb is too cold. I'd ask your locals what's the best season in SF Bay.
Anyways, here's what I do on San Diego Bay when I can't afford live bait:
I use 1oz to 2oz leadheads, with 3" to 5" plastic swimbaits in anchovy or sardine colors:

Or same size curltail grubs in white, orange, pink/red.
I tie a little Xmas tree tinsel behind the leadhead / before the plastic and let it trail for some flash, and put a strip of cut squid on the hook for flavor.
I use 60-80lb dacron braid for my main line, with 2 or 3 feet of 20-30lb mono or fluoro for a leader. This cuts through surface kelp, lets you feel everything down there, but gives some shock absorbance on the strike and you can break free if you hook into the bottom or a giant ray or something.
I target 25-40ft of water, right along the edge of the channel just before the dropoff, with sandy bottom, on a large incoming tide (4'+ best), starting 2-3 hrs before high tide right up to an hour after, ideally all this taking place before 11am-12noon (which is when the winds really kick up here).
Then I let out 20 or 30 yards of line, just drift with the tide, ideally 1.5 to 3 knots, speed and course controlled via drift sock (i.e., bucket on a rope) and/or electric trolling motor. I cover a lot of ground this way, just bouncing the leadhead up and down off the bottom. And if I do get a hookup (or a miss), I'll go back and go over that spot again, because Halibut do tend to congregate in an area.
There are times when the wind and current confound efforts to drift on the course I want. In those cases, I'll drop the leadhead, let out 150-200 yards of line along the course I want while motoring with the electric, then reel-and-bounce. This is another good reason for dacron braid, because you can set the hook from 200 yards with that stuff.
I always keep a couple rigs like this on the boat even when I am planning to use live bait, because sometimes all the bait barge has is 6-7" monster sardines, and that bait's too big for my tank and too big for the bay (or more accurately, anything I could safely handle alone that would go after such bait

)
This setup in the San Diego Bay will of course mostly turn up those 21.5" not-quite-legal flatties, but occasionally will hook up one of those 22-30", 6 to 20 lb fish that are just so damned tasty
