This question is popping up in a couple of threads so let me help out with a few ideas.
Always calico bass so if you are into that, bring the gear, probably a bit heavier that usual because the weeds are thick. Weedless rigs, i.e. big slug baits with buried dropshot hooks, weedless leadheads with that toothbrush thingy under the chin, etc.
Always rockfish if you are on the east or southeast side of the island. Couple of 2 hook shrimp fly ganions with heavy weight. Islander cruises around and will call you in on a spot. Or you can easily find the spots on your fishfinder. If the big game fishing is slow, no harm in filling up the bag with taco meat.
Halibuts very likely so bring this gear. I've caught them on fishtraps, carolina rigs and a kayak sized bounce ball rig I put together.
Yellow tail, maybe so be prepared just in case. Irons, dropper loop and fly line.
WSB, rarest of the all, but you never know.
Bring a sabiki or two. Sometimes the bait is marginal and sometimes they just want to eat mackerel.
Hope that the bombing is subsided and you can fish Pyramid Cove, one of the world's best place to kayak fish.
Don't bring all the tackle you have in your garage. Less is more. Have your gear organized so when you are on deck to rig your yak, you can get in the water ASAP. Otherwise you hold up everyone behind you.
The cabins only have a one dual outlet so two guys with multiple chargers,
bring a multipoint outlet strip.
Last time I was out, they had nice local microbrews in the reefer. But is doesn't hurt to bring your favorite. Share a nice Ballast Point Grunion or a shot of Bushmills with some of the regulars and you may pick up a tip or two.
And have a great time!
