I would definitely just take the very basics for the first few trips and then decide what YOU really have a need for. Like you, I had no prior experience kayaking.
When I took possession of my new Outback, the dealer threw in a basic cart, which I have used once I think. I fish out of the port daily and ended up buying a small trailer to make my life easier. I still have basic fins and rudder, I'll upgrade to turbo fins and sail rudder eventually, but do fine with basics for now.
I initially added a drive leash for the reverse drive. It's fantastic, especially if you fish structures a lot. Rodleashes are also a must have. Pretty much everything is tied up, even if you dont tip over, it's easy to loose stuff overboard.
IMO a comfortable life preserver and a flag/light combo are the other first and most important additions.. Next a VHF, I went with Standard Horizon HX870.
After the first few times out, I added an anchor trolley (I like the leverloc) and 3 pound anchor (plus retractable clothesline mod), set up an old rectangular milk crate with 3-rod holder on back, knifes strapped on the side, waterproof tackle boxes and a 5 Gallon bucket with bubbler for live mullet, shrimp, etc. inside the crate. I also keep a set of fishgrips in there and attached a couple of rolls of mono/fluoro leader, long de-hooker, measuring tape. The crate is straped in with the rear bungies.
I added a Lowrance Hook7 which I run on a 15 amh jet ski battery, it was cheap ($35) and works great all day (downside is the 10 lbs weight, but it works out fine for me). I initially had a small net, but it turned out fairly useless, changed it out for a small gaff instead.
I installed a rectangular hatch (went with a white one from Duckworks Boatbuilder's supply because the round black Hobie hatches warp like crazy when out in the sun all day). I use an Ortlieb foldable sink inside it for easy access to small stuff, rags, phone, scissors, pliers etc.
35 liter shallow tubtrug in the front compartment where I store flares & first aid, a froggtogg rainsuit, extra rags, another tackle box with spare swim baits, a headlamp. Large fish cooler bag buckled over the bow hatch.
Usually take 2 rods, sometimes a third for a baitfish rig.
I just added a Scotty rodholder, comes in handy but more of a want not need...OK so thats a lot of stuff but hey, I got completely addicted to kayak fishing since having to give up other passions-you only live once. And by far the best exercise and therapy for a bad back and wore out joints.
Oh and a phillips screw driver because the hinge screw on the left side of my seat keeps backing out, weird- tried threadlocker, lockwasher, nothing works so I just keep screwing it back in. Real pain when the backrest comes apart from the seat...
Fish on, c u on the water
