After a lot of trips, too many to count, I want to add some cheap things and ideas to your list. Here comes the WalMart ad.
Rain X - treat your sunglasses or readers with Rain X. They stay clean half a day.
Equate arthritis rub - Walmart's brand of Aspercreme which does wonders for sore hands. $3.
Equate Self-adhering bandages - same as flex wrap, one-third the price.
Equate Clear Lax - Don't wreck your trip or everyone else's with a medical
evacuation. I've personally been on two ultra long trips that were wrecked by someone else's constipation. Don't be an
asshole or a
shitty fishing story. (All puns are deliberate)
Butch Green got it right. His or the Bowen 19" box fits in every boat's tackle rack. They are small. Even filled, they are not heavy. Only the top opens. It keeps gear dry. Big boxes and most of the new boxes with too many drawers and front doors suck for many reasons.
The rest of your tackle, those $30-50 lures and all the rest can stay high and dry in the spare stateroom bunk. Refill your deck box as needed. Soft sided hard bottom tool bags from Home Depot, Amazon, or WalMart are cheap, hold tons of gear, have strong carry straps, don't spill or break, and keep things dry if it's raining at the dock or some deckhand gets sloppy with the hose when you're unloading after a long trip. Wet cardboard and rusting $800 of lures would not be my first choice.
Boxes are OK below decks but these tool bags are better. Hooks, wire, leaders, swivels, jigs, flat falls, tuna clones, and 20# of sinkers. Several small bags are far better than one big one.
If you put all your gear on the deck in one big box, you're inviting a wave to douse and rust everything.
Same deal for reel bags. Nothing fancy. Snap On from Amazon or Home Depot. If you want dividers, use a towel since it has other purposes too.
Don't rig all your rods. Rig only the rods you might need tomorrow, a troller, a jig stick, a bait rod. Leave the spare rods bundled in the stateroom until you need them. Your roommate will hate you for a trip, but your rods and reels will love you for life. Everything on deck requires a thorough cleaning. Gear stored below doesn't. Anyone who rigs up all twelve of their rods on the way south is making a big mistake.
And here's a couple of things you don't see listed very often in anyone's list.
This is a cable carrier from Snap On. It's perfect for big coils of mono, fluorocarbon, wire, or wind-on leaders. It organizes all your leader gear.
Next to the leader bag is Penn Warfare. If you fish long enough you'll have a trip where all the bait dies. When that shit happens, you will fall in love with this stupid cheap reel, the Penn Warfare push-button level wind. It's just for fishing bait. Fill it or any level wind with depth finder multi-color braid so you know how deep you're fishing when you find bait. It will save you a ton of work.
If you use a duffel for your clothes, use the side zipper variety, not the military style. You won't have to tear everything out to find something at the bottom.
Finally, don't put your dirty clothes in a spare plastic bag. I don't mind doing laundry, just not wet, moldy, stinky laundry. Get a real mesh laundry bag at WALMART.
, Keep your extra rods that your not fishing with in your stateroom 
. Don't worry about tour room matte's feelings, he may hate you but your rods and reels will always love 
. You must be "That Guy". WOW
