Boat Day Essentials: Everything You Need for a Perfect Day on the Water

A great boat day is all about preparation. Once you leave the dock, there's no running back for forgotten sunscreen or a dead speaker. Whether you're on a pontoon, a ski boat, or a friend's fishing rig, this list covers everything you need to bring — and the things most people forget.

The Non-Negotiables

These go on the boat every single time:

Sunscreen (SPF 50+) — Water reflects UV rays, so you burn faster on a boat than anywhere else. Reapply every 90 minutes. Bring both spray and lotion.
Water — One bottle per person per hour, minimum. Sun, wind, and beer all dehydrate you. Freeze some bottles the night before to double as ice packs.
Cooler — A hard-sided cooler for a full day, soft cooler for a quick trip. Pre-chill it the night before. For our top picks, see the best beach coolers roundup.
Towels — Two per person. One to dry off, one to sit on. Quick-dry towels save space.
Life jackets — Required by law in most states. Have one per person, properly sized. No exceptions.

Drinks

Beer — Cans only. Plan 3-4 per person for a half day, more for a full day. Light lagers are the boat beer standard — see our best summer beers for what to stock.
Hard seltzer — The co-pilot to beer on any boat. Light, refreshing, low mess.
Water and electrolytes — Mix electrolyte packets into a few bottles. You're losing more than you think.
One batch cocktail — A jug of ranch water or vodka lemonade goes a long way. Our summer beer cocktails are perfect for pre-mixing.

Food

Keep it simple. Nothing that needs a plate, fork, or refrigeration beyond your cooler.

Sandwiches or wraps — Pre-made, cut in half, wrapped in foil
Chips and salsa — The universal boat snack
Fruit — Grapes, watermelon chunks, and orange slices. Pre-cut and in a container.
Jerky and trail mix — Salty, satisfying, no prep
Popsicles — Freeze them and toss them in the cooler. Everyone loves boat popsicles.

Gear

Bluetooth speaker — Waterproof is non-negotiable. JBL Flip or Charge series are the standards. Bring it charged.
Dry bag — For phones, keys, wallets. A $15 dry bag saves you from a $1,000 problem.
Tube or float — At least one per boat for pulling behind or lounging at anchor
Sunglasses with a strap — Polarized to cut glare off the water. Croakies or a similar strap so they don't end up on the lake floor.
Hat — A trucker hat or wide-brim for sun protection. Your scalp is the first thing to burn.

The Stuff Everyone Forgets

Lip balm with SPF — Burnt lips ruin a boat day faster than anything
Hair ties — Wind plus boat speed equals tangled mess
Trash bag — Pack out everything. Tie it to the boat so it doesn't blow away
Extra phone charger — You're taking photos all day. A portable battery pack is essential
Light layer — A hoodie or flannel for the ride back when the sun drops and the wind picks up
Boat shoes or grippy sandals — Wet fiberglass is slippery. Bring shoes with grip.

What to Leave at Home

Glass anything — it breaks and sinks
Valuables you can't waterproof
Hard coolers too big for the boat
Anything you'd be devastated to lose overboard

FAQ

How much ice do you need for a boat day?

About 2 pounds per person per hour. For a group of six on a full-day trip, a 20-pound bag plus frozen water bottles is a solid baseline. Pre-chill your cooler overnight for maximum ice retention. See our lake day packing list for more detail.

What should you wear on a boat?

Swimsuit, a cover-up or rash guard for sun protection, grippy sandals or boat shoes, sunglasses, and a hat. Bring a change of dry clothes in a bag for afterward. For swimwear that stays put during activity, check our best bikinis for lake day.

How do you keep food cold on a boat?

Use a separate cooler for food (or a section of your main cooler that you don't open often). Freeze water bottles and pack them around perishables. Keep the cooler in the shade and limit how often you open it.

What's the etiquette for being a guest on someone's boat?

Bring your own drinks and a snack to share. Arrive on time. Ask before you board. Help clean up after. Don't wear shoes that mark the deck. And always thank the captain — boat ownership isn't cheap.
