I know a few people that have been on these trips.
Most of the time you have no issues bringing home probably way too much fish.
Does one really need 150lbs of yellowtail and 150lbs of tuna in the freezer? Probably, not.
Is one willing to pay the cost of processing the fish at $2/lb hanging weight? Probably the most shocking thing after a 7k fishing cruise on the ocean, is the 1.5k processing bill.
Most do not filet fish on the boat.
Have a plan before hand on what you are going to do with the fish. An air BNB is probably a decent option with a little folding table, a vacuum sealer, and 5mil pre cut bags.
LR boats get the best bait (cured) at the bait barge in SD and sometimes you will have to make bait.
You will have a lot of travel time 2-4 days depending on the length of your trip.
Your liver will thank you if you bring items to read or entertain yourself with rather than just drinking the entire time.
Most are sponsored trips with giveaways at the start.
However, you probably should have a bunch of terminal tackle and potentially a few jigs or wahoo bombs.
LR boats have the best sleeping arrangements of any of the SD fleet and probably have some of the best crews and chefs as well.
If you drink a lot (Not legal advice, but it is technically illegal), then it would be wise to bring some of your own booze on the trip.
If you are a drunk obnoxious a-hole, you will be sent to your room.
So, control yourself and find something outside of drinking to do when you travel to and from the fishing ground.
Follow the other recommendations from the outfits and remember to take sunscreen or UV shirts.
Being severely sunburned and splashing salt water around is not a good combination.
Also, bring finger tape or gloves.
For fishing yoyos and vertical jigging with a conventional reel and guiding the line back into the reel.
Line cuts and salt water is not a good time, and can be decently painful at times.
