I have the same boat, just older. Things I have added in addition to what you already have on yours.
1. Raw Water Washdown
2. Trolling motor (if you fish) + batteries & charger.
3. Trolling motor may require you to move your nav light. I went with Taco Surface Mount LED lights & love them.
4. Switch out that leaning post with something that has storage under the seat & a fold down foot rest (optional, but nice if you spend any amount of time in a no wake zone.
5. A nice to have is a ROKK Wireless Waterproof Phone Charger.
6. I personally have the Lenco (9X12" tabs & I find I use them all the time. I do have the 150HP on the back, but the tabs def help with weight shift as your crew moves around.
These are great little big boats for sure. I fish out of NJ as well and I've been in some pretty nasty unfavorable conditions & I never felt unsafe.
